In 10years will probably in history books only, Ethereum and real platform like ethereum are the only ones which will survive the crypto bubble.
I suggest you take some time and read the following article by the Co-founder of Blockstack:
https://medium.com/@muneeb/the-road-ahead-for-ethereum-b5b090bcd1aEthereum, in my view, has taken on at least three hard Computer Science problems.
Its unclear if any of them can be solved in a practical sense. Whats worse is that the
broader Ethereum community believes that Ethereum already has the solutions or is close to having them.
People have been trying to find a solution for these problems for several decades without success.
What makes you think that the Ethereum team that is prone to postpone development milestones
will have more success than the bright minds, who researched this for decades?
Ethereum has maybe 1-2 years left and then it will eventually disappear due to the unsolvability
of these hard Computer Science problems.
