What do you do with your junk coins? almost all new Altcoin don't have good prices to make a profit.
Will there be a rule about a good project that doesn't produce junk coins? Disappointing.

If there is no opportunity to sell them at least at some price, then I keep them. Sometimes they can grow well in value and make a profit. I already had such a case, when I earned several Ethereums on a junk coin.
