With the rise in difficulty, the coin is already not profitable, the average price of BEAM is around $1.10 which is not sustainable.
for 1080ti average sol/s = 15
for 1070 average sol/s = 9
current Network hashing rate is 2.5Msols/s or 2,500,0000 = 166,666 gtx 1080ti.
Profitability calculations are as follows:
(Miner sols / Network Sols) X (1440 x Reward per block)
1440 min because 1 block generated per min
(15/2,500,000) x(1440x80) = 0.6912 BEAM approx per day per 1080ti =0.76 cents per 1080ti before electricity cost.
Good luck to the project hopefully price will go up.
Mate you need to install new miner - gminer 1.17
