I spread mine out coz i honestly dont know how far itll go.
i put 500k at .000005 - this is kinda my stopper so i can try recoup hardware costs. I think itll hit this quite easily - maybe not soon, but when the block rewards halve (please dont shout at me !)
ive then put a few mill between .00002 and .0001 at different intervals. Ive kept some in my wallet too just incase and will continue mining til block halving.
