Financial suicide has nothing to do with ending your own life, and I don't think that's what Kara3 was getting at there.  But I think you're both wrong anyway.  You're not ruining your finances if you don't hold bitcoin; many people around the world don't, and they're doing just fine.  I'd love to see Kara3 look Warren Buffett in the face and tell him that line:  "Mr. Buffet, if you don't own bitcoin it's financial suicide!".  He'd probably just chuckle and politely excuse himself as he would if some person with a crackpot stock strategy started extolling the wisdom of following said strategy. 

Note: I'm not saying being extremely pro-bitcoin is a crackpot position, just making a comparison in the specific case of a chat with Buffett.
