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.
That could be true. However our total supply will not be in circulation in the beginning or at any time in the near future. With in the first 10 years, we project only 150 billion coins to be in circulation. We are not producing a short term, in and out coin. We are offering a long term solution to many peoples problems. Currently, most people are not accepting crypto currency because of the negative connotations that come from the dark corners of the internet...and the early majority hasn't even started to join the market yet. Crypto currency is still relatively new to the currency industry....so in regards to "keeping the laymen out", only time will tell....
