I would only take some global crypto into consideration like ETH, BTC, LTC or BNB. Those coins are fundamental and you cannot go wrong with them. Especially at the moment, when BTC halving is nearing from day to day.
Newbies should start with the top and basic coins in their portfolio, coins that are on the top 5 are really worth compiling in portfolio, then just add more coins after you done your research, the top basic can can give you an insight and quick profit, do not be tempted fast on those pump and dump coins, that people here are shilling, some of them are trap, you can lose everything on these coins.
