Also we can expect something completely new that can cast shadow on bitcoin and other coins..
Nonsense.
I think if blockchain will collapse it will be the end of bitcoin transactions.Because all bitcoin transactions is going under blockchain and being confirmed by blockchain.If blockchain will be down who will confirm our transfer? How can the users receive it without any confirmations from block chain.Thats what im thinking.
It's obvious that you're lacking the relevant knowledge. The blockchain can not simply "collapse" (the word is also very wrong).
The Bitcoin price climb, and the one post wonder shill posters increase. This is pure fud being posted to create confusion.. not to be taken seriously at all.
It doesn't surprise me anymore.
If by "blockchain collapse" you mean no internet anywhere then sure Bitcoin would be worthless because no one would be able to use it.
That's just one of the possible scenarios, but things like Bitcoin would not matter much in the times of total catastrophe.
