ethereum classic is one of the most successful forks ever done (like BCH, one of the most successful forks done on the Bitcoin network), in 2016 the price of each ETC was close to $ 1, and although It could not maintain its growth in 2017-2018, but the current price is still many times higher than the first price.
In my opinion, considering that this network was introduced to improve ethereum and provide a better version, it would have been much better to use the PoS algorithm instead of the PoW algorithm, because PoW causes a lot of problems in principle, and I'm sure if ETC uses PoS Used, now its price was several times the current price.
