first of all most of the people dont know what they are talking . BTC will not be dead there is a big community which is holidng it .
If somewhere there will be information about the fact that Bitcoin goes Q2 or begins to die, then I would advise you not to pay attention to it at all. Because If a person does not have reliable information, then one does not need to take negative information for the truth. This is all information manipulation to provoke a panic in the Bitcoin market. Many users, thanks to such manipulations, buy up Bitcoin in huge quantities. Canceling Bitcoin will still go up.
Bitcoin has scaling issues and conflicts of interest that cannot be solved with its current consensus mechanism. In this great experiment of decentralization ironically the miners supporting the network have coalesced into Pools, of which 6 control over 50% of the hashing power and as a result could collude to manipulate the system in their favor (51% attack). This is as effective as being "decentralized" over 6 nodes.
Bitcoin Inspired us, but like the Wright Brother's first plane, its destiny was never to be an airliner.
What will "replace" Bitcoin? - as a decentralized platform for payment and exchange, personally I think Bitshares will.
Stop thinking about Cryptocurrencies as currencies and start thinking about them as Companies. The ones that are organized as such, IMO, will ultimately succeed over the ones that aren't because everyone works together to form consensus and drive the organization in a positive direction towards growth.
For example, as you will see in the coming weeks, Bitshares is about to host a competition which will distribute the most prize money in history. $1,000,000,000.
https://steemit.com/hero/@stan/the-billion-hero-challengePeople will cling to Bitcoin out of emotion and hope that they will be able to solve the problems in the future... just like with Ethereum. However there are platforms, like Bitshares, that have already solved these problems and are driving towards world wide adoption today.
Bitcoin is dead, and like a grieving mother to a deceased child, it's investors will cling to its lifeless corpse.
