I think a reasonable approach to investing in Bitcoin lets say 1000 USD is :
The worst what can happen is that you lose the 1000 USD.
The best what can happen is that you make possibly 350 x profit = 350 000 USD
So maybe worth the risk to invest in Bitcoin...

Actually, you can't lose $1000. For this to happen, Bitcoin will have to go to zero, which is not very realistic. Every next cycle's bottom is around the previous cycle's top: previous cycle's top was around $69k so if you invest now, you can't lose anything, you can only gain or break even at worst.
