To be Fair and honest
Btc will go highest high and then will collapse!
Becouse bitcoin dont have much of utility its expensive to exchange in to fiat currency.
Slow confirmations.
But there is solution: xrp is solution Low fees and Fast transactions.
I give maximum life time for btc 2 years then it will collapse, reason is simple expensive fees and slow confirmations.
I just want to concentrated on these point that is emphasising on bitcoin collapse, for bitcoin to go up does not mean that it will collapse because in 2017 bitcoin get $20k in values, so since 2017 till now has it collapsed the answer is No, when saying collapse do you mean in price or btc generally will collapse.
If it's in price its obvious that it can collapse as you said, because it's increments in price never remains constant at period of time, but via btc in generally, I don't think it's acceptable.
