Can orther explain about its a good point else about the risk its to high to lose to lot on it?
Mining altcoin may profitable if the demands are pretty high but just some coins are worthy I thought such as icn.
Well, I don't rely on altcoin as I didn't get into trading yet. I prefer to saving bitcoin due to the best cryptocurrency ever.
If you feel that those coins are profitable than continue to mining and sell some, if not than leave it.
