Video show us that genesis mining is real company and legit.
Yes, it is a real company.
I bought little contract. What better choose for mining BTC or LTC today?
Not sure, I would go for Dash oder Monero. Afaik the difficulty hasn't been raised as much as for BTC. And so your loss won't be so huge.
Have fun!
Monero isn't worth it in my opinion. GPU mining might still be more profitable, the price for getting the contract might about just pay itself off. Right now Eth and XMR are better mined with GPUs yourself. The prices are too expensive in my opinion.
