After former FTX CEO Sam Bankman-Fried (SBF) filed for bankruptcy, investors have lost millions to what former UBS Americas CEO Robert Wolf calls a "ponzi scheme." One investor shared his reaction to losing $2 million in the disaster.

"This is a big lesson for everybody in the crypto community," investor Evan Luthra said on "Cavuto Live." "It's a big, strong lesson that, not your keys, not your crypto. If you don't hold the keys to crypto, it's not really your money."

Luthra also responded to new details in the Wall Street Journal that SBF pocketed nearly $300 million from funds raised last October, slamming the former CEO for using the exchange as "his personal bank account."

"This was all intentionally done," Luthra added. "This was a very calculated plan, or I should say a crime that has taken place."

Since the debacle, concern over the security of cryptocurrency has grown, but some like Luthra remain confident in the virtual currency.

"You could have a car manufacturer who cut some corners and then defrauded the industry. Doesn't mean electric vehicles are bad. So it's like bitcoin by itself, the fundamentals are still very strong and if you have bitcoin in your hard wallet, in your hand, you have not lost any money today," Luthra said on "Cavuto: Coast to Coast," Thursday.

"From all this fiasco I've already come to realize that Sam Bankman-Fried is a bad actor here," Luthra said on Saturday. "We already know that this is a bad actor, this is a fraud, this is a criminal."

As investigations continue into SBF funds and the operations of FTX, many are calling on lawmakers to return donation funds to the victims of the sophisticated scam. Democrats in particular received a large sum from SBF, with only some returning funds so far.

Luthra argued blame for the incident lies with FTX and the leadership under SBF, not the lawmakers who accepted donations. 

"You can't blame the government for accepting donations without knowing that this was going to be criminal," Luthra said. "You can't really blame anybody in this case except Sam Bankman-Fried who is cruel, who intentionally planned and executed a fraud against the whole community and everybody involved."

Luthra echoed calls for lawmakers to return funds.

"But the right thing would be for them to give the funds back whoever got the donations, and it should go back to the victims whose fund it really is."

"This was never his money to give away," Luthra said. "This was our money."
