How do you mine within client?
Same way you do with Bitcoin, use the setgenerate command.
On the surface level, a new trader who looks at the total supply might be turned away by the 186 billion total, even if it is going to be distributed over 100 years.
It's much longer than 100 years, half of all coins will be mined in 100 years. But if they choose to turn away based on a quick glance then it's their problem.
Realistically, this coin won't reach age 100, I'm doubtful any crypto will. We will be playing with some other digital currency form by then.
Well then it doesn't really matter either way, the end result is the same, a smaller coin supply for the time we do use it.
Thanks BF.
