Even though I am not a fan of cloud mining services as I have always been critical of their business because its the most abused platform to scam innocent people of their resources but that being said I don't think they could have made any other decision due to what is being faced by them and what we have been reading on the clamping down of mining sites in China as well how difficult it is to do business, they have no option than to increase their charges. But I still don't see the justification of up to 50% from 6% that is way too high and it further elongates the long period of time one have to wait to ROI in the first instance.
