Well, investing in shitcoins is definitely bad, but I really don't see a problem with trading shitcoins. Also, why is it a waste of time? If you can make more money off it to increase your bitcoin holdings, then what's the problem with it? Trading doesn't automatically mean taking part in pump and dumps.
Obviously, shitcoins don't give us any outcome and it's a waste of time. Expecting something which doesn't happen is the reality of investing in shitcoins, I am good with Bitcoin and I believe in this because it's a real competitor in the market and it will boom very soon.
