I don't think its is safe to host your miners there since they are someone already posted a scam thread about this ..
If you wanted to safe your investment better to mine your own in your place than just hosting your miners .
I couldn't invest and just to find a hosting company for miners .
This is just my suggestion if you wanted less risk for your investment better to mine in your area which is more safe than you are using other third party companies..
