The huge ETH fees are creating opportunities for others to step in with a solution. I've seen you mention Cosmos/Atom which is worth looking into. Polygon/Matic seems a good alt to ETH and easy to buy on hive-engine. Zksnarks I think was taking about a token airdrop like UNI did, if you have made any trades with it.
I'm really interested to see what PulseChain is going to do when it launches soon as a full state ETH fork. I love what our Hive fork of Steem has done, which was also a full state fork where we were given matching Hives for all our Steems. PulseChain will create matching tokens for Eth and everything on Ethereum. Its block time is 3 seconds, its fees are very small, and some Pulse is burned on each transaction and there is no inflation so always less Pulse over time. Hundreds of millions of dollars were sacrificed to possibly receive Pulse tokens so there seems to be lots of interested money in this project.
Now they are receiving hundreds of millions in sacrifices for PulseX, a Uniswap clone for Pulse. And there's LiquidLoans offering 0% loans on Pulse after a fee, so like the Hive Bonds and Hive CD ideas, and like HEX the original CD crypto project, people are incentivized to Hodl and not to sell, while still having a path to some liquidity via tax advantaged loans.
Time will tell if ETH can hang on to its legacy spot in the crypto hierarchy. The challengers are on its tail and may surpass it. Exciting times!
