Investing in a shitcoin is very similar to investing in a ponzi scheme. Everyone knows that ultimately it is going to become worthless. But for some people, the greed is so great that they want to book profit using such assets. To tell the truth, there is a chance of profiting out of shitcoins. They will undergo several pump and dump cycles. If you are really really lucky... then you may be able to sell them during a pump and book good amount of profit. But the chances are that you may be unlucky, and may incur losses in 90% of the cases.
