Has BlockFi ever been hacked?

I want to use BlockFi but first I want to know how safe it is. Has it been hacked before?

BlockFi has been hacked. But critics say it does take security seriously.

Gemini is BlockFi’s primary custodian and BlockFi doesn’t hold private keys directly.

Gemini keeps the vast majority of its assets in cold storage and is insured by Aon.

Gemini is a licensed custodian and regulated by the NYDFS.

Block Fi says that implementing a short waiting period has been critical in protecting clients from hacking attempts.
