Hi All!
I started my first BTDX masternode (i hope I did well). Its run. I want to started my second masternode. How can I? I buy second VPS
(It's cheaper than I would buy an IP address.)?
What's the genkey? Same?Big thanks!

You would need to setup an second VPS, make a new transaction for the collateral, generate a new masternode key (genkey), adjust your second bitcloud.conf and masternode.conf.... and that's pretty much all there is to it.
So you run a VPS per masternode and you can control them all from the same cold wallet.
