I tried to start the masternode on Vultr.

I was facing a problem after transferring chain coins in two transactions on the same account(Wallet) . Its showing that 1000 chain coin are present after more than 100 confirmation now. But when trying to start Masternode this message is coming.

chain coin not capable masternode: Could not find suitable coins!

Again then I withdraw then send back again in new wallet and master key in one transaction but again same message.

 chain coin not capable masternode: Could not find suitable coins!

What it means and how to overcome this problem. Kindly guide.
