Spreading it over 100 coins will be advisable.
Definitely not. 100 coins is too spread out. There's going to be a significant chance of you getting in on scamcoins and shitcoins on those 100. 20 coins/tokens is definitely enough in my opinion. Though it ends up depending on which specific coins/tokens you actually invest on.
I agree. We don't have 100 worthy coins on the market. Do you really want to put your money into another worthless BTC fork?
Sure, we could put some money in a shitcoin hoping that some pump group gets interested in it, but the risk is just too high. It's better to be safe than sorry. ]
No smart investor goes after shitcoins with real money. Those are newbie playgrounds that attract people with very little money who think that buying a fraction of BTC is much worse than buying 100 cheap shitcoins that aren't all together worth even 0.1 BTC
