I’m becoming increasingly concerned with the security of the Bitcoin Integration because of the node operator collusion attack vector of the tECDSA subnets, please see here: Threshold ECDSA Signatures - #202 by lastmjs
I’m not entirely decided, but personally I don’t think I’d trust much of my BTC on the IC at this point, and having $millions of people’s funds on the IC will make me feel very uneasy.
