That's not true at all. Most cryptos aren't clones of BTC at all - they have wildly different consensus systems, interaction models, goals and capabilities. They all have their own issues and capacities, but saying they are all clones of BTC is like saying all existing programming languages are clones of FORTRAN and have the same problems as FORTRAN does. There's a huge variety, and we're still in the very beginning of it, nobody knows what emerges out of it and what would be successful and what would fail. It's probably decades in the future, maybe more.

Ethereum is also part of the shitcoins given the ridiculous amount of premined, but their marketing is considerably better.

Most crypto are running on Ethereum at this point. A lots of useless Bitcoin clone indeed.

But a lot is happening still. Heck, I think some of those chains even serve a actual purpose, without the computational issues. Crazy right ?

As for Bitcoin, I hope the money in it trickle down to actual useful things. But, trickling down. Well, we know how it goes .

Can you list the problems here? For each problem I'll give you an alternative of Bitcoin that aims to solve it. I'm not joking.

That you for proving their point.
