https://www.genesis-mining.com - accepting VISA / MASTERCARD------------------------- just don't understand what "lifetime bitcoin contract"means
Does that mean mining for you forever ?
There are contracts only valid for a certain amount of time, like 12 months or 5 years.
Lifetime means they won't expire as long as the company/service exists. In reality, it means: It's valid until we get hacked/robbed and you will never get your funds back.
Source? Check LTCGear, Hashie, AMHash and others.
I can only recommend to stay away and keep your funds. No profit is better than a loss.
No, it means it (your contract) will keep mining until it is no longer profitable (doesn't cover the electricity cost).
