I prefer to choose Genesis Mining than Bitdeer because I already tried with both in the past. Bitdeer gives you a discount for buying the hashrate to their machine, but you should pay the electricity to them. It's not worth it because your profit will be reduced because of the electricity fee and that will happen too in Genesis Mining. Right now, the cost to buy a big hashrate is not worth getting the reward from the mining because you should calculate the electricity fee that will need you to pay.
