If you must hold altcoin because they always bring better profits do not go too deep and make sure your altcoins are top altcoins
New and cheap altcoins also will give huge profits but 99 out of 100 will go in the opposite direction so you can reduce the risk of losing your investment capital by holding well recognized altcoins.Still no one can predict which coin is going to be more profitable 2020.
Absolutely right, Because i have invested all my money into altcoins and that time i made profits after that i have lost nearly 99% of my capital. But i have invested in the top altcoins, i can now enjoy recovering my fund but i am now hopeless for investing in shitcoins. So research before investment is necessary for every new investors.
