There is no simple or professional DC.
If you pay for simple DC, mr fly will mine the price difference with your miner and will come up with an excuse.
Your miner crashed, your miner is overheated, your miner stopped connecting to our router.
No compensation in these cases.
Sales has dried out for mr fly, he got use to money. So you will see him taken advantage of our miners more often.
Better send your miners to one of the US based DC for better rates and reliability.
