To me ETH's model is like oil, you need to purchase it to use their computational power of the network, the more complex the transaction and fast the more oil/gas you use. I think since it was the first token tool, it has first mover advantage and ALOT of assets are built on top of it.

I think it will always be around but BTC will gobble up most of the alts that don't have a unique solution. Lightning will kill any speed focused coins, RGB network will bring tokenisation to Bitcoin (which we already see running on BCH) so why would I care about having all these wallets if my BTC wallet for example can hold USDT and other tokens.

Yes the other chains will help with throughput, but I don't see anyone beating BTC
