It won't matter anymore when the next Bitcoin halving is here, that 6BTC per block will be reduced and a 110TH will have only 1% chance of solving a block compare to when it was 2%, the difficulty will rise more and the block will bring only 3BTC. There are many people doing solo and they don't have any luck while someone with less TH will solve a block in few months, It's a game of lucky.
