Zac Prince, Founder of BlockFi

According to the complaint, the crypto company BlockFi, Inc., controlled by collective BFI defendants Zac Prince, Flori Marquez, Tony Laura, and Jennifer Hill, sold unregistered securities to class members.

The unregistered securities sold by the BFI Defendants, including Founder Zac Prince, were marketed and sold over several years through misrepresentations, material omissions, and intermittent misrepresentations by Defendant Gemini Trading LLC.

Details of The Lawsuit Against BlockFi Founder Zac Prince

According to the lawsuit, BlockFi’s founder, Zac Prince, made false and misleading statements to promote BIAs, including that BIAs were a safe way to collect interest.

Furthermore, the Complaint alleges that the Defendants omitted and concealed material information regarding the risks associated with BIAs, including through BlockFi’s exposure to FTX Trading, Ltd. and Sam Bankman-trading Fried’s firm Alameda Research, both of which collapsed following revelations that FTX and Alameda were engaging in massive fraud.

Did You Know?

FTX stands for ‘Future Exchange’. FTX was one of the largest exchange platforms for digital currencies. The purchase and sale was recorded in crypto. FTX trading is trusted by many. However, FTX Trading Ltd. is quite dubious.

The lawsuit asserts that BlockFi stopped withdrawals from BIAs following the FTX crash, affecting BIA investors.

Additionally, BIA investors were unaware of conflicts of interest and self-dealing between BlockFi and other companies, like Gemini Trust LLC, which Tyler and Cameron Winklevoss control.

The complaint further claims that by offering and selling BIAs to investors, BlockFi and its founder Zac Prince violated Sections 5, 11, 12(a)(2), and 15 of the Securities Act of 1933.

Moreover, charges of violations of Massachusetts General Law Chapter 110A and Sections 10(b) and 20 of the Securities Exchange Act of 1934 are made in the action.

BlockFi Overview

About BlockFi

BlockFi was founded in 2017 by Zac Prince and Flori Marquez as a digital asset lender. Its headquarters are in Jersey City, New Jersey. It was once worth $3 billion. In July 2022, the cryptocurrency exchange FTX announced a deal with an option to purchase BlockFi for up to $240 million.

Initially, the company focused on crypto-backed loans, allowing individuals and institutions to borrow cash or stablecoins as collateral against their crypto assets. This service quickly became popular among investors looking for liquidity without selling their crypto holdings. As a result, BlockFi has established itself as a reliable player in the crypto lending space.

How BlockFi Works

BlockFi is a web platform and mobile app for buying, selling, and trading cryptocurrencies. Accounts of BlockFi can be funded via ACH, wire transfer, or cryptocurrency deposit.

BlockFi provides the following services besides cryptocurrency trading:

  • Crypto storage through a wallet service
  • Crypto-backed loans
  • A crypto rewards credit card

BlockFi also offers interest-earning accounts for all of its cryptocurrencies.

How BlockFi Makes Money

BlockFi generates revenue through four primary channels:

  • Withdrawal fees 
  • Trading fees 
  • Interests in crypto-backed loans 
  • Rehypothecation

Withdrawal fees are the fees users must pay when they withdraw funds from their platform. Trading fees are those charged on the total value of the trade, whereas interest in crypto-backed loans is the amount BlockFi earns for making these loans available to its users. Finally, rehypothecation uses collateral assets pledged to it as if they were its own.

Fees Overview

BlockFi does not charge cryptocurrency trading commissions. It instead charges a margin based on the asset’s price. The margin is typically around 1%, but it may be higher if liquidity for that cryptocurrency is low.

Withdrawal Fees

BlockFi charges fees for cryptocurrency and wire transfer withdrawals. It does not charge fees for ACH withdrawals to your bank account.

The following are BlockFi’s withdrawal fees:

Bitcoin (BTC)0.00025 BTC
Ethereum (ETH)0.0135 ETH
Chainlink (LINK)2 LINK
Litecoin (LTC)0.001 LTC
U.S. dollar stablecoins (GUSD, USDC, BUSD, PAX, DAI, USDT)$25
PAX Gold (PAXG)0.035 PAXG
Uniswap (UNI)2.5 UNI
Basic Attention Token (BAT)60 BAT
Wire transfer$20 (domestic), $30 (international)

Loan Rates & Fees

On all crypto-backed loans, BlockFi charges a 2% loan origination fee. The interest rate ranges between 4.50% and 9.75%. It is calculated using the loan-to-value (LTV) ratio, which is the loan amount divided by the amount of collateral provided. Borrowers who provide more collateral benefit from lower interest rates.

BlockFi’s interest rates and the LTV ratios:


BlockFi Interest Account (BIA)

The BlockFi Interest Account is the name of the interest-bearing account. Interest can be earned in BTC, ETH, LTC, USDC, GUSD, and PAX. There is no requirement for a minimum balance.

BlockFI Interest Accounts (BIA) are no longer available to new clients who are US citizens or residents of the US. Existing clients who are US citizens or are based in the US will be unable to transfer new assets to their BIAs. The BIAs have not been registered under the Securities Act of 1933. They may not be offered or sold in the United States, to US persons, for the account or benefit of a US person, or in any jurisdiction where such an offer would be illegal.

This account is only available to non-US residents and is provided by BlockFi International, a subsidiary of BlockFi (Bermuda).

Is BlockFi safe for your cryptocurrency?

BlockFi has security standards, but the fact that it offers crypto-backed loans poses a risk during periods of market volatility. To assess BlockFi’s safety, we will first examine its security features and then the potential risks of its lending program.

One of the main risks for BlockFi is that it accepts cryptocurrency as collateral for cash loans. These typically have an LTV ratio of 50% or less, implying that the collateral is worth at least twice as much as the loan. If the value of the collateral falls, the borrower must add more, or BlockFi may liquidate its position.

BlockFi lost approximately $80 million in 2022 when one of its large clients, Three Arrows Capital (3AC), failed to increase its loan collateral. As a result, BlockFi was forced to sign a deal with the FTX exchange.


Rosen Law Firm, a global investor rights law firm, filed a class action lawsuit on behalf of investors in BlockFi Interest Accounts (“BIAs”) between March 4, 2019, and November 10, 2022, against BlockFi Founder Zac Prince, Flori Marquez, Amit Cheela, David Olsson, and Samia Bayou. BlockFi is a digital platform that offers a crypto wallet, crypto-backed loans, and live crypto trading.

The Complaint alleges that the Defendants omitted and concealed material information regarding the risks associated with BIAs. The complaint also claims that BlockFi and its founder Zac Prince violated Sections 5 and 11 of the Securities Act of 1933 by offering and selling BIAs to investors. Furthermore, the action alleges violations of Massachusetts General Law Chapter 110A and Sections 10(b) and 20 of the Securities Exchange Act of 1934.
