Is anyone concerned with Cardano/Solana/Algo eating into ETH? Speculative concerns here.

With the recent uptrend in other ecosystems and consistent discussion about bridges being built to ERC-20 tokens, is anyone else slightly concerned about the network effect of these other block chains eating into ETH? Gas is high. Ecosystem is large.

Each of the others I mentioned have smaller ecosystems but with bridges and cross-chain-comparability discussed, what’s the long term thinking?

Solana has grown, and is cheap and fast and PoS. Algo, more centralized but super cheap and fast. Cardano, ok, no smart contracts YET but allegedly coming in hot, super cheap (alleged) and super fast (alleged)

I’m speculating a bit here, but I am concerned about investing a chunk into ETH atm.

Talk to me cryptoverse. What am I missing in my concerns and where am I not seeing things.

GLTA,DYOR ETC ETC ETH… ETC..
