Shitcoins can cause your portfolio to suffer with a tendency to lose capital most of the time.
A shitcoin is a shitcoin, no need to entertain the idea of investing in it, even if you could profit from playing the game. Just focus on the dark side—shitcoins are scams. If you're making money from it, that means some investors are losing. It might be acceptable if the ones losing have no idea they’re investing in a shitcoin, but if someone knows it’s a shitcoin and still sees an opportunity to profit from it, that’s almost like a crime. You’re benefiting at the expense of others.
Note that Bitcoin is the only long-term investment worth investing in, if you ever invest in anything other than Bitcoin, chances of losing money are high. Because only DCO method invests your bitcoin for future years it will not be destroyed, but if you choose altcoin directly to get more profit then it is maximum stupidity and more likely to be destroyed which will run out of money. So if we are thinking of long term investment then surely we will choose Bitcoin following DCA method no doubt. Because your investment will last longer and you will be more self-reliant.
