Its easy to say 'Bitcoin will fail', a 2 yr old could say that and have as much integrity as the op. Want to impress me?  When is it going to fail. So far, and when I say bitcoin I really mean blockchain technology used to trade work between 2 parties, with high security.

So I ask you OP when is bitcoin going to fail as a method to transfer currency from one person to another anonymously?  So far, it hasn't failed, its passed with flying colors everytime there is a transaction added to the blockchain that cannot be reversed ever.

I'm waiting for the date that bitcoin or blockchain technology fails. please.

I think your 'Question #1 is totally irrelevant.
