I was around and saw it first hand when alt coins first launched Ethereum, Dash, Peercoin, BTS.
All with dreams and high hopes built on fraud like an MLM scheme.
How does it end? they have their cycle of a bull run outperforming Bitcoin for a short period of time followed by a slow painful decline, there's a reason we don't hear from the "Dash, D Cash" crew anymore, there's a reason we don't hear from the "Green" Peercoin yes they too had their, .Ether, Binacian, Dot communities.
What could happen? the year could be 2026 and you won't hear a peep out of Ethereum, Binance people due to shame and the connection to ignorance of these ecosystems.
I have no interest in "altcoins" and only followed a company called Tzero that tried to utilize legally the ERC-20 method to launch digital securities and guess what happened? they ended up shutting down operations due to ERC-20 on Ethereum simply not working or having a suitable model.
Digital currencies, tokenization are experimenting with ERC-20 in house clones that operate internally with no token, as logically if institutions will adopt something like an ERC-20 standard they will just create their own like they're doing not relating to Ethereum's token.
There is a major reason leading institutions are warp speeding Bitcoin spot ETF applications and not "altcoins".
If history repeats I suspect altcoins like Ethereum / BNB / SOL / DOT to slightly follow the pull of Bitcoin but underperforming and eventually when Bitcoin is in a late stage bull run capital will bleed and bleed out of them back into Bitcoin.
Lets see how this ultimately plays out, I expect when Bitcoin makes a move to $90,000 if Ethereum has not orbited near $6,000 the lost of trust in the alt networks will accelerate and the demise will start, you will see the communities like the last start panic followed by turning on each other followed by Bitcoin accumulation.
