anyone reach miner 40 lvl?
i found is hard to reach the top lvl, i am at lvl 10 now, and mine 2 hrs to grow 1%, means i need 200hrs or about 8days for lvl up.

assume same speed for the following lvl, i need 30 x 8 =240days, however i believing lvl up is getting harder for higher lvl, so it might take about 300days to reach the max lvl eventually.

please share your experience as high lvl user, thanks.
