If you will buy many tokens and leave it on different exchanges then you might forget it.
Though if you will ahve it on your wallet and do like blockfolio and some others, then keep tracking the telegram group and their pages then you can hang tight.
For me it is better to have many coins than a few, this will give you more goods.
FOr me too many coins/tokens will give you a pain.
You should seek for some few real good tokens on your wallet and focus on it.
Like 10 coins will be good as long as htey have the best potentials, then harvesting too many which could lead you to worng way.
