When can ETH catch up with BTC?
This will never happen , sorry about that but you cannot expect a Shitcoin to cover the main crypto like bitcoin .
so Basically it is better to look in different side than believing what you think can happen here.
It is. Ethereum has been catching up on btc ever since before because as we can see, eth never losses its spot as a second rank crypto but I guess that's the only thing it can do and eth will never surpass btc no matter how hard it try because like you said eth is just a shitcoin and many people are not a fan of shitcoin.
What stability is he talking about? I can't seem to see it but what I see is a very volatile market but stability isn't only the basis that a bull run is coming. How many times this market is being volatile and yet we are still seeing some bull runs but not all that will sell at a bull is going to be rich because not all have a massive coin available to sell.
