I don't see anything wrong in diversifying ones investment when you have all it takes and you have the capacity to manage your investment judiciously but it becomes wrong and bad when you don't have the capacity to do both at same time and again even if you want to diversify, your Bitcoin investment should be your priority. However, shifting focus from Bitcoin investment to shitcoin and altcoins is not advisable but in the outside world you need to try everything in order to survive.
It’s really a nice idea to diversify your portfolio, but in the process of trying to diversify their portfolio, most people do end up making a great mistake, they do end up investing in wrong altcoins, have seen people invest in shitcoins which is really a wrong investment plan, I don’t think anyone should even plan to hold shitcoin for a long period of time, it’s totally wrong, because shitcoins are always hyped, and immediately the hype dies down, then they will never rise again, shitcoins doesn’t have any future.
If you are planning to invest, then just focus on bitcoin, and if you are planning to diversify, then do your research, and leave little amount of money in strong altcoins, altcoins that have been in market for some period of time, but avoids memecoins, and shitcoins.
