I have only 10 TB, will I ever win XCH on mainnet?
Starting with the new consensus algorithm in Beta 19, there are 4608 chances per day to win 1 TXCH (and thus XCH on mainnet.) If you have 10TB and there are 30PB of total storage on mainnet then you would expect to win ~1.5 TXCH per day on average. The math is .010 PB/30 PB * 4608 = 1.536.
