I think mining is not profitable and reliable at this cryptomarket situation because the market fluctuate is too high also BTC suddenly dropped to $4k this is not good to mining field.
Bro, it's not mining using hardware but it's mining cloud, and fraud can occur if we are not careful about Mining Doge.
The OP says we have to invest 100 DOGE with 800 DOGE outputs, is this a joke?
I think we should be careful with this type of Mining Cloud, please check all the security of their website.
