We have to be honest. Neither Ethereum nor Ethereum Classic (no fries with a Coke) are really scaled and both suffer from severe design problems penalised by bottlenecks, fees, and a shift to POS sitting the oligarchy of price manipulating whales. While Bitcoin is not a 100 meter race, it is a marathon of big blockers, the only one scaled for this global utility competition. If you want Bitcoin to succeed then it's very simple: use it and don't waste time on broken or obsolete systems that can't really evolve (or else they would have done so long ago)!
It's strange that no one notices that all these blockchains take years to try to replicate Bitcoin to tamper with it. Did you know that Ethereum was created from Bitcoin script? I remember that at the launch of ETH there was a company that sold ETH in premine and then the company disappeared after the people who bought the premine received their ETH. It seems that many people have forgotten this, by the way there would be much more ETH in premine than we were led to believe. ETH and ETC are useless, drain industrial funding unnecessarily, consume precious resources, are non-evolutionary so that actually 8 billion people and as many connected iot devices can use them, in short ETH, ETC, BTC, SOL and many others are fucked.
That said, don't get caught up in stories of these ready-made manipulators who are after your finances by making you believe that their software allows you to..... almost nothing.
Bitcoin is an experiment, the pillar that paves the way to other things, societal, economic, and technological, it is a highly secure peer to peer bridge to connectivity between machines, financial systems and far beyond; but I won't tell you more, it's up to you if you want to go down to explore the rabbit hole.
