All the skeletons it has. Big exchanges going down, ponzi schemes, scams, drugs and so on..
Instability in its price is to me the least favorite thing about bitcoin.Another one is it require miners to confirm your transaction and if you dont add fat fee to your sending amount..
Is 4 cent fee a fat fee for you? Then quit bitcoin and go to your bank that charges you 2% + 5$/TRANSACTION.
I think trolls like you are one of the least favorite things.
