For newbie, who is just involving in crypto world, I suggest you buy the top, promising coins, not the new ones. Coz you don't have experience to trade new altcoins, which may be scams, pump-and-dump, company coins or clone one etc. You may end up losing your money.
pretty much this. Best advice anyone can give you.
Stay away from new coins don't matter how promising you think they are. Stick with old coins and if you feel inclined to invest in new coins ..don't invest over 1% of your total investment.
