FULY.AI runs the world's largest crypto lending community and regularly hosts member finance seminars covering crypto investing, asset allocation, traditional finance, overseas real estate, smart loans for investment immigration, tax compliance and filing — essential financial-literacy topics.
After years in the industry, FULY.AI has built a deep network in crypto. We warned users to withdraw days before FTX collapsed, helping them avoid losses. We also pioneered member-only seminars on withdrawals and taxes to help members minimize investment risk.
FULY.AI is the bot service that understands the Bitfinex lending market best — offering the most complete hands-on tutorials and paid 1-on-1 advisory services to meet every learning need. Our founder personally answers user questions as customer support.
FULY.AI's large Bitfinex lending community attracts countless partnership offers from exchanges and projects. For years we've refused paid endorsements, refused to run private funds for outsized profits, and refused to fleece users — earning user respect in a wild industry.
In addition to refusing paid endorsements, FULY.AI has never paid "non-users" or KOLs who became users just for sponsorship. Every KOL, YouTuber, and finance educator who publicly recommends FULY.AI is a genuine user. We believe only real-user recommendations carry true reference value, so we have declined many high-profile KOL marketing pitches over the years — choosing only to do what's right.
If you're a FULY.AI user who loves our service and is happy to recommend us, and you happen to run your own community or channel, we'd love to chat — no matter where you are. Reach out via customer support DM.
Toward financial freedom, starting now
Bitfinex lending — formally known as Margin Lending — is the funding source traders draw from when they engage in margin trading (borrowing spot or capital to open leveraged long or short positions).
In simple terms, Bitfinex lending is similar to traditional brokerage margin financing. The difference: with stocks, the broker sets the rate. On Bitfinex, the exchange's matching platform uses an order-book mechanism, where lending rates are set by orders placed by funders and borrowers.
Bitfinex and USDT issuer Tether share the same parent group, iFinex. USDT is the world's largest USD-pegged stablecoin by issuance, circulating across major exchanges globally. According to Tether's reports, USDT is over-collateralized — primarily by short-term US Treasuries. By the end of 2025, Tether's US Treasury holdings exceeded those of many countries, making it one of the largest creditors of the US government.
Bitfinex and Tether share a common destiny. Because Tether holds enormous quantities of US Treasuries, a USDT collapse would cause violent price swings, fire-sale selling, and possibly a Treasury default — an outcome the US government would clearly want to avoid.
So is Bitfinex safe? We can say: if USDT is safe, Bitfinex is safe. As long as the US government doesn't target USDT, USDT will be safe — and because USDT is safe, the US is safe too.
That said, no investment in the world is 100% safe, and no bank or country is too big to fail. Investors should still evaluate carefully and diversify to minimize risk.
Bitfinex was founded in 2012 and is one of the oldest exchanges in crypto, having weathered many black-swan events. Still, no investment is 100% safe — diversify your assets to minimize risk.
If prices crash rapidly (over 30%), the system's auto-liquidation mechanism may not be able to sell collateral in time, potentially leaving borrowers unable to repay. This has not occurred on Bitfinex historically, but cannot be ruled out for the future.
Lending is mostly in USD or USDT. When converting to fiat, exchange rate swings may cause FX losses, plus remittance fees should be factored in.
Borrowers can repay anytime. With manual lending, if you don't bid immediately, your funds sit idle (with interest accrued by the second), eating into returns.
Bitfinex lending isn't a bank deposit — there's no guaranteed yield or fixed rate. Returns vary widely depending on lending strategy, lending mode, and the bot used.
According to FULY.AI lending-bot statistics, the average annual yield is roughly 10%~25%, depending on yearly market conditions. Generally, the more volatile BTC and ETH prices are, the higher the rates.
Without using Bitfinex auto-lending or a lending bot, yes — you'd need to monitor it 24 hours a day.
Yes, borrowers can repay at any time within the loan term.
No. Bitfinex lending isn't a bank demand-deposit account. Only borrowers can close early, or repay early after liquidation. Lenders cannot demand early repayment before the agreed term ends.
If a lender needs to withdraw funds, FULY.AI users can manually shorten the lending period and set a "Reserved Amount" so the bot doesn't immediately re-lend idle funds after a borrower repays.
With the FULY.AI lending bot, daily interest is automatically lent out as principal once it accumulates above USD 150 (Bitfinex's minimum order size) — no setup needed.
Because of how Bitfinex lending works (instant repayments, no auto-compounding, etc.), lenders without automation tools have to invest enormous monitoring effort. FULY.AI solves these problems and, with its proprietary order-bidding algorithm, delivers 150% the returns of manual lending.
It's the safest, most time-efficient, and highest-yielding automated lending solution.
Daily interest is paid at UTC+8 09:30 — no need to wait for the loan to be fully repaid. Interest above USD 150 can be auto-compounded.
The barrier is very low — just over USD 150 to join the funder ranks and start earning.
