No one really knows when, 4 months after you post this, and the market is still just go up and downs, not bullish. It will likely go sideways until at least the halving of bitcoins. Except the altcoins can fully independent not affected by bitcoin price, but that things is also unlikely in near future. So, I think everyone should just expect a sideway market for the meaning time. And for the question about eth and btc? I don't think ethereum can catch bitcoin in near future, or even it will never, bitcoin is too strong.
whales still accumulating cryptocurrency since few months ago, alot hard dump and pump happen recently which make alot sell or long liquidation.some altcoid could hit ath eventhough bitcoin price dumped. Zil , gmt , ape could be an example how strong coins with good utility in market.ethereum price will follow bitcoin price move paralelly.
market clearly in bearish trend now since luna foundation guard dump their bitcoin with huge number only to pegged ust price. no altcoin could defend from this crash even gmt and zil also dumped hardly.but i am agree token with good utlity will survive longer in market for long term although in short term its bearish.
