Earning cryptocurrency online with little investments, but big interests

Below are my Bitcoin Referrals, underneath code or link are my comments:

Hashflare:

Code: E0ECE9E
They don't sell lifetime contracts anymore. But they are still reliable. Based in Estonia, probably run by Russians.

Genesis-Mining.com:
Code: 0P6Bgy
Mostly out of stock. They are reliable. Run by Iceland.

Bitconnect:

They still exist despite of problems. Registered in England. I call them Thailand based, because they had a meeting there.
They are promising to return investment.

Chinese company, I hope it lasts.

Aurum Bank

Registered in England as many others. Probably run by Russians. Still there, sometimes website problems.

It's kind of new mining company, probably run by Chinese. But they still sell lifetime bitcoin cloud mining contracts.
Their contracts are more expensive than GenesisMining or Hashflare.
