With 1 billion coins, it's gonna be hard to make good profits from this coin.
Any particular reason for such high supply?
The project is very interesting nonetheless and I am in.
The total supply has no correlation with the possible profit. There are lots of coins that prove that. The amount of investments is. e.g. if you invested 1eth and there were 100000eth invested, in the case of huge succes your profit will be less than when just 1000eth were invested.
We need a 1 billion marketcap for the coin to reach $1. I don't think this is very easy to achieve. Beyond $1 involves a 1B+ marketcap, something very hard to believe in the near future.
There are only 7 coins with over 1B marketcap, 8 if we count IOTA (keeps switching below and over).
