For those who are unaware, 20% of all mined minexcoin goes directly to MinexBank.
This means as long as they maintain the server and internet for the website and its wallets, and people are still mining, and EXMO keeps trading in MNX, then it isn't going to die. Only a minimum of maintenance is required. And for 30% APR? go ahead and mention your 5% coins, your 4.08% websites, and your 1.5% coins...
They can sip fruity drinks delivered by bikini models in the bahamas, pumping and dumping whenever they feel like it, I'm getting 30% APR. You know what I get at the bank? 0.25%.
I'm just saying, you do you.
