TRON Buys BitTorrent: A 100-Million-User Acquisition and the Token That Followed

TRON’s purchase of BitTorrent is usually filed under founding trivia — a headline acquisition early in the project’s life. For investigative work it is more than that, because the acquisition produced a tokenA unit of value recorded inside a smart contract rather than in the chain's native ledger — the contract keeps the balance table, and moving tokens means asking the contract to update it. Not to be confused with a coin, which is the chain's built-in asset (TRX on TRON) used to pay for the network itself., the token was distributed by a specific on-chain method, and that method is something you still encounter when reading old TRON walletsSoftware or hardware that stores private keys and uses them to sign transactions. A wallet holds keys, not coins — balances live on the ledger itself — so the same funds can be reached from any wallet loaded with the same keys, and losing the wallet loses nothing if the keys are backed up elsewhere.: a passive BTT airdrop landing in any addressA public identifier, derived from a key pair, at which an account receives funds and is looked up on-chain. Anyone can view an address's history, but only the matching private key can spend from it. TRON addresses are 34-character Base58Check strings beginning with "T". that happened to hold TRXThe native coin of the TRON network. TRX settles value directly (no contract call needed), is staked to obtain Energy, Bandwidth, and voting power, and is burned to pay fees when staked resources fall short. Its smallest unit is the sun: 1 TRX = 1,000,000 sun..

That distribution method later became a load-bearing part of the SEC’s case against Justin Sun: a product decision from 2018 turned into an on-chain pattern in 2019, then a legal allegation in 2023. This article traces that arc end to end.

The acquisition

The deal closed in July 2018. BitTorrent’s own announcement, dated July 23, 2018, confirmed it — “BitTorrent is now part of TRON” — and the TRON Foundation’s letter to the community followed a day later. Both framed it as a merger of vision: “BitTorrent and TRON share the same vision for a decentralized Web.”

The path to the close was less smooth than the announcements suggest. According to contemporaneous reporting, Sun first approached BitTorrent in late 2017 and signed a letter of intent in January 2018, and the deal was briefly held up when BitTorrent began talking to other bidders — prompting Sun to file for a temporary restraining order to keep it on track. Those deal mechanics rest on press accounts; no first-party statement covers them, and this article treats them as reported claims.

The price is genuinely unsettled. The widely-cited figure is $140 million in cash, but documents filed with the California Secretary of State suggest Sun paid closer to $126 million. Neither the BitTorrent blog nor the TRON Foundation letter disclosed any number at all. What can be said for certain is a range: a deal reported at roughly $126–140 million, with no official figure on record.

What TRON bought, and why

The nine-figure price bought reach. BitTorrent’s announcement put the user base at “over 100M users around the world” — a peer-to-peer file-sharing network that had been one of the most-installed pieces of software on the internet for over a decade.

The strategic logic, in TRON’s own framing, was to pair a high-throughput blockchainA shared ledger maintained by many independent computers, in which transactions are grouped into blocks and each block cryptographically references the one before it. Because rewriting any past entry would break every link after it, the record is effectively append-only — new entries can be added, but history cannot be quietly altered. with an established mass-market user base and call the combination the largest decentralized internet ecosystem in the world. The TRON Foundation letter cast the merger in movement terms — to “liberate the Internet from the stranglehold of large corporations” and “give data rights back to the individual.” Stripped of the rhetoric, the asset was distribution: a hundred million people already running software TRON now owned, and a plausible story about rewarding them in a token.

The token did not exist yet; it came six months later.

The BTT token

On January 28, 2019, BTT launched through a token sale on Binance Launchpad. The mechanics are documented first-hand in Binance’s own announcement: a total supply of 990 billion BTT, of which 59.4 billion — 6% — was sold in the Launchpad event at a price of 0.00012 USD per token.

The sale ran as two simultaneous sessions — a BNB session of 23.76 billion BTT and a TRX session of 35.64 billion BTT — and, by Binance’s reported results, sold out in under twenty minutes, raising on the order of $7 million in TRX and BNB combined. BTT was pitched as a utility token — the announcement tied it to BitTorrent Speed, a feature that “rewards users with BTT for sharing files in a peer-to-peer network” — which carried the acquisition logic through: the file-sharing user base would earn a token for bandwidthA TRON network resource that covers the byte-size cost of putting a transaction on chain — one byte consumes one Bandwidth point. Every account receives a small free daily allowance (also called free bandwidth); heavier usage requires staking TRX, receiving a delegation, or burning TRX to cover the bytes. it was already contributing.

The airdrop to TRX holders

The Launchpad sale put 6% of BTT into the market. For TRON wallets, the airdrop mattered more. It asked nothing of recipients and it recurred monthly, reaching anyone who held TRX — no purchase involved.

The BitTorrent Foundation ran the first BTT airdrop on February 11, 2019, distributing 10,890,000,000 BTT — about 1.1% of supply — to every TRON address holding at least 1 TRX, at a ratio of 1 TRX to roughly 0.1098 BTT. It was not a one-time event. The Foundation laid out a multi-year monthly schedule: airdrops on the 11th of each month, scheduled to run yearly through 2025, with the annual percentage rising 0.1% per year from 1.1% in 2019 toward 1.7% by 2025. Distribution was automatic — as the Foundation stated, BTT would be “automatically distributed to the TRON (TRX) holders, regardless of whether TRX are frozen.”

The passivity matters when reading wallets. A wallet did nothing to receive BTT except hold TRX on the right date, so a BTT airdrop in its history is a signal about the wallet’s timing and balance, not its intent — the activation mechanics of these passive token arrivals are covered in the field-book chapter Airdrops and Faucets. Early BTT places the address in the program window and nothing more; who controlled it, and why, stays open.

How the airdrop became a securities case

When the SEC charged Justin Sun and his companies on March 22, 2023, it named BTT alongside TRX as a “crypto asset security” offered and sold without registration. The recurring airdrop — four years old by then, and to that point resembling a loyalty program — was not treated as incidental. The complaint alleged that Sun, the BitTorrent Foundation, and Rainberry “offered and sold BTT in unregistered monthly airdrops to investors, including in the United States, who purchased and held TRX in Tron wallets” — making the monthly distribution program itself one of the unregistered offers. The complaint also described “bounty programs” that directed people to promote the tokens and “create BitTorrent accounts in exchange for TRX and BTT distributions,” and alleged the tokens were promoted by paid celebrity endorsements without disclosure.

The case’s procedural arc — through amendments, a litigation stay, and a March 2026 resolution in which the claims against Sun and the two foundations were dismissed — belongs to the Justin Sun and the SEC article, which is the canonical home of the regulatory timeline. For BTT the point is narrower. The BitTorrent Foundation’s 2019 announcement described the monthly airdrop as a feature; the SEC’s 2023 complaint described it as an unregistered securities offering. Both documents are describing the rows of BTT transfers an investigator can still pull from the chain.

What it means for an investigator

A BTT airdrop in a wallet’s history is a dated, passive distribution event — useful for timing, weak for attributionThe process of identifying the entity most likely to control a blockchain address by combining on-chain signals — who created and funded it, how it transacts, which keys can act for it — with known service patterns and labels. Attribution conclusions are evidence-weighted judgments, not certainties, and are strongest when several independent signals converge.. It tells you the address held TRX during a specific program window and received tokens automatically; it does not tell you who controlled the address, and it never created the wallet’s relationship to anyone but the distributing foundation.

Two clarifications keep that reading clean. The original BTT was a TRC-10 token distributed by the acquisition-era program described here; BitTorrent Chain — the cross-chain network sometimes abbreviated BTTC — is a separate, later development covered in bridges, not part of this story. And the acquisition itself, like the Steem episode and the SEC case, is one node in a larger pattern of Sun acquiring infrastructure and user bases across the industry; the origin and architecture of TRON places it in that wider arc. For the wallet in front of you, the BitTorrent history reduces to one fact: BTT arrived because TRX was there. The mechanism that delivered it is the one the SEC’s complaint later described.

A note on sourcing: the acquisition price is presented as a contested range because no official announcement disclosed a figure — the $140 million headline is press-reported and corporate filings indicate roughly $126 million. The letter-of-intent and restraining-order deal mechanics are press-sourced and presented as reported, not first-party. The Launchpad sellout time and ~$7 million raise derive from Binance’s own reported results; the supply, allocation, price, and session figures are confirmed directly from Binance’s first-party announcement.
