Coins that does'nt belong on top 100 alts have more risks on buying compared to top coins that belongs in top 100. I don't recommend buying those coins
but there are some coins that has low marketcap that is being under valued. Buying coins that has low marketcap brings you high risk but you will also be
given a high reward if you have chosen the right coin for you. If you are planning to buy alts that is not on the top 100 because of the current rally of bitcoin today
I would suggest that wait for the price of bitcoin to go sideways as there would be a high chance that all alts including the top 100 coins will suffer when bitcoin
continues to go up.
