Thinking about investing in an asic miner. I pay a flat rate for my electricity, so electricity cost is not an issue, only the upfront cost of buying the equipment and the total amount of power I can draw from my MCB.
If I order from China to UK, say an S9, is there a customs fee, and if so does anyone know what it is? Or if I should buy directly from a UK seller (2nd hand or ‘new’).
Even with zero electricity cost, is it still profitable to mine the SHA algorithm with say an S9, bearing in mind the increase in difficulty as it is in the near future. Likely to make my ROI?
Otherwise, what would be the best ROI as it stands atm. The GMO B3’s look really sweet, but it’s a long way off till dispatch (nov ish).
