BlockFi has emerged as a key player in the cryptocurrency financial ecosystem since its founding in 2017. Designed to bridge traditional finance with blockchain innovation, BlockFi offers a suite of services including crypto-backed loans, interest-bearing accounts (for eligible users), trading, and a rewards credit card. This comprehensive review explores BlockFi’s offerings, functionality, security measures, and recent regulatory developments to help investors determine if it aligns with their financial goals.
What Is BlockFi?
BlockFi is a New Jersey-based digital asset platform founded by Zac Prince and Flori Marquez in August 2017. The company aims to empower users globally by combining the accessibility of crypto with the structure of traditional finance. While not a bank, BlockFi functions as a crypto custodian and lending platform, offering services such as interest accounts, USD loans backed by cryptocurrency, and seamless trading—all without transaction fees.
One of its standout features has been the BlockFi Interest Account (BIA), which allowed users to earn competitive interest on crypto holdings like Bitcoin (BTC), Ethereum (ETH), and stablecoins such as USDC and GUSD. However, due to regulatory scrutiny, new U.S. customers can no longer open BIAs. Existing U.S. clients may maintain their accounts but face restrictions on adding new funds.

How Does BlockFi Work?
BlockFi operates on a spread-based revenue model. It borrows crypto from users at one interest rate and lends it out at a higher rate, profiting from the difference. This model powered its former BIA product and continues to support its loan and credit offerings.
Today, BlockFi generates income through:
- Interest spreads on crypto loans
- Fees from its credit card program
- Trading spreads (though no direct trading fees are charged)
The platform serves both individual and institutional clients, enabling them to trade major cryptocurrencies, borrow fiat currency using digital assets as collateral, and access premium yield solutions for high-net-worth investors.
Key Products and Services
BlockFi Interest Account (BIA)
Available only to non-U.S. residents through BlockFi International (Bermuda), the BIA allows users to earn daily-compounding interest paid monthly. As of mid-2022, rates included:
- 6% APY on BTC
- 8.6% APY on GUSD and USDT
- 4.5% APY on ETH
No minimum balance or hidden fees apply. For U.S. users, BlockFi is working to launch BlockFi Yield, a SEC-compliant alternative currently in registration.
Crypto-Backed Loans
BlockFi enables users to borrow up to 50% of their crypto’s value in USD without selling their assets. With interest rates starting at 4.5%, these loans require no credit check—only sufficient collateral in BTC, ETH, or LTC.
A 50% Loan-to-Value (LTV) ratio must be maintained. If market volatility causes the LTV to rise (e.g., BTC price drops), users must deposit more collateral or risk liquidation.
Cryptocurrency Trading
BlockFi supports trading in major digital assets including:
- Bitcoin (BTC)
- Ethereum (ETH)
- Litecoin (LTC)
- PAX Gold (PAXG)
- Stablecoins: USDC, USDT, GUSD, DAI
Trading occurs at competitive prices with a typical 1% spread between bid and ask prices. There are no trading fees, though withdrawal fees apply after one free monthly withdrawal for select coins.
BlockFi Rewards Credit Card
This Visa card offers crypto rewards:
- 3.5% back in crypto for first 90 days (up to $100/month)
- 1.5% thereafter, increasing to 2% for annual spending over $50,000
To qualify, users must have a funded BlockFi account and join the waitlist.
BlockFi Wallet
A secure, non-interest-bearing wallet for storing supported cryptocurrencies. While most assets can be transferred freely, U.S. users face withdrawal restrictions on DOGE, BCH, and ALGO.
Personalized Yield & Trusts
High-net-worth clients with $3M+ in assets qualify for Personalized Yield, featuring dedicated support, negotiated rates, and lending opportunities.
Accredited investors can also access BlockFi Trusts (Bitcoin, Ethereum, Litecoin) with a $50,000 minimum investment and 1.75% annual fee.
Security Measures
BlockFi prioritizes security through:
- Cold storage via trusted custodians like Gemini, Coinbase, and BitGo
- Mandatory 50% LTV for loans to reduce default risk
- “Allowlisting” feature to restrict withdrawals to approved addresses
- Full KYC verification for all users
While not FDIC-insured, BlockFi’s U.S. presence and partnerships with regulated entities enhance trust.
Customer Support and Mobile Experience
BlockFi provides 24/7 customer support via email and phone, with a well-organized help center categorized by service type. Its mobile app (iOS and Android) enables users to trade, borrow, monitor balances, and earn interest on the go.
Educational content is available through BlockFi Live, its YouTube channel covering tutorials and market insights.
Regulatory Challenges and SEC Settlement
In 2022, BlockFi settled with the SEC over unregistered securities offerings related to its BIA product. The settlement required:
- A **$100 million penalty** ($50M to SEC, $50M to states)
- Immediate halt of BIA offerings to U.S. residents
- Plans to register a new product under securities law
This move reflects broader industry trends toward compliance and transparency.
Fees Overview
| Service | Fee |
|---|---|
| Trading | 0% fee; ~1% spread |

| Withdrawals | Free once/month for select coins; fees apply thereafter |
There are no account maintenance or minimum balance fees.
