No. It depends of the price and repartition.

Bitcoin with 21 millions is way too low.

Not even everybody on the planet can get 1  bitcoin....

Anyway as an investor you should only see for the price, repartition, technologie and the potential arrival of new investors. You should explain why you think it's too much.

If i buy for 10k$  i will get more Stellite than Dash but finally the value still 10k$. I think that presently there is no "way too much" in total supply in the world of cryptocurencies. The price can be way too low or too high, but not the total max supply (it can be too low but not too high with 21B, or like i said it depends of the repartition, you can't just take in count the max total coins only)
