Coin supply waaaay too high.
Define too high? Why is this number too high? I understand why you say that, we want the value to be low in the beginning. We don't want any pumps.
Too high is relative to the number of people using the medium of exchange. This debate probably belongs in an economic sub-forum. IMO the OP's argument for having such a high number of coins (that dev wishes for the coin to be used in the real world) has already been proven false through Bitcoin. You expect people new to crypto to accept all of the zeros in front of the coin's price. That annoying feature alone is enough to keep the layman out.
