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.

This is a free market, mate. Everyone can issue their coins, even you. It's their right. Your responsibility is to protect yourself from these trash coins.
If it is like this then I think people should not trust those fake and trash coins when we have better options in our market. For me instead of buying and trusting New currency I prefer to invest my money for bitcoin and ETH. Crypto market is free and open for everyone so you are right it is our duty to stay aware of scamming and unknown projects.
