The reason is that shitcoin is very low price and if we are going to sell it we only get penny or a very small amount of profit the worst thing is if we buy that altcoin in a high price and end up all into shitcoin, thats considered as loss. The only solution for that matter is selling even if we got loss as long as we can sell it even in a low price we need to sell it and change it to good altcoin for good.
