ETC rank is currently number 26, this is a pretty good position because it is a potential coin and remains at the top. Although I am not a lover of ETC, but I have benefited from this coin in the past. Currently I only focus on the top 10 coins. If you still feel ETC is good for investment, you can try it.
ETC experienced impressive price increases during the bullruns 2017 and 2021, yielding significant profits for investors. However, to be honest, I don't have high expectations for its price increase in the bullrun 2025 as it has become technologically outdated and faces a major competitor - ETHW. If investors prefer POW, they are more likely to choose the newer ETHW instead of the older ETC.
As you've pointed out, ETC has fallen out of the top 20 and has become less accessible to crypto investors. Nevertheless, those who favor ETC can still include it in their portfolios during this bull run. After all, ETC price recovery to its equilibrium price zone could still generate profits for ETC holders in the bullrun.
