Keep in mind that SHIB has a supply of 1,000,000,000,000,000 and growing with no maximum supply. So it would need to have a market cap of 10 trillion just to hit a penny. So it would have to get 10x bigger than BTC is currently. I wouldn't suspect any institutional money to flow into SHIB or DOGE, they are terrible, inflationary protocols than have no utility. So it will be a lot of small money coming in opposed to big institutional money like ETH and BTC. Doesn't mean market cap couldn't 5x up to a $100 billion, there's actually probably a decent chance. Just beware on meme coins, they dump 10x harder than they pump. But, may as well let it ride, just realize it's a 50/50 gamble play. There's a good chance people that bough the DOGE hype may never see their money as interest moves onto the next meme coin. Meme coins only have so many buyers, and as more coins pop up, the money is getting spread thin. That's why DOGE isn't recovering while the rest of the market is. I think there are much better projects that actually do something at a very low market cap that are much more likely to 5-20X than SHIB or DOGE.
Also beware ETC and ETH are very different. ETC has been propped up by people thinking they're buying ETH. So as ETH grows, it is likely that ETC may grow as well. But again, institutional money won't buy it. ETC is the original ETH blockchain. After their hard fork, ETH was proven to be much better and was essentially the winner. Very few people are developing on ETC while something like 80% of all crypto projects are on the ETH network.
