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.
It will be fair if you can tell us the highest high you are talking about and the level of the crash you forsee. It is not good to thrash a thing because you feel the need to make a post. If we view it closely by the way, 2 years is enough for anyone to expect a correction. And if it eventually happens it is nothing bad because nothing goes up forever.
In the aftermath of the last collapse of bitcoin after attaining ATH in 2017 shoud have been used to justify your theory or speculation however despite the odd bitcoin rally up again even in this period of pandemic remained unscathed thus I don't believe in any speculative analysis of 2 years life span of bitcoin, meanwhile scalability issues of bitcoin will be well addressed and solved thus facilitating faster processing of transactions and improved Lightning Network will also take care huge fees paid on transactions thus all these theories wouldn't hold water.
