Asic is a piece of iron. It is expensive, on the secondary market is not in demand. As a rule, it's very dinny and consumes electricity. The profit falls very quickly, only those customers who will receive the first are the winners + problems with the guarantee.
The GPU has fewer problems and can be sold in the secondary market
I agree with you but asics dramatically increase the complexity of the network and make mining GPU unprofitable. You have no choice. I do not agree that all who buy asics in the first batch have time to return their money. I do not believe that anyone will return their $ 10,000 invested in asic even with a capacity of 50 Ksol
I agree, no one will be able to get their ROI. Current profits are not reflect real difficulty in just few weeks later. The people making money is the manufacturers.
