Does that mean it wouldn't be worth mining with that CPU?
A few months ago the price of a YTN was $ 0.5, and now only $ 0.03 worth has been reduced by more than 10 times, it is difficult to return to the original value.
YTN's original price before coinsmarkets fall was around $0.12. When CM fall STEX became the only available exchange - then pump and dump happens.
After that people jump in and net hash tripled. STEX Dump + coins from miners lower YTN price to current price. It's hard to gain buyer's trust again.
