I put $10 dollars and expected earnings for 1 year are about $20. That's 100% per year.
When compared to ViaBTC, which uses AntMiner s9 the most perfomant miner to date:
Price: 0.21 BTC Per SHARE
Minimal Amount: 1 SHARE
Estimated Daily Earnings: 0.00068045 BTC Per SHARE
Yearly earnings: 0.00068045 * 365 = 0.24836425 BTC
Which is about 18%.
ViaBTC seems to be a reputable pool.
There is something that does not fit here.
