Exclusivecoin (EXCL) has a Masternode system, you can get one for about 900 USD at the moment. You need 10.000 EXCL and each costs 0,09 USD = 900.
Right now you can only buy this coin on Bittrex. But on their Twitter page, I heard that this coin will be added to a big exchange in the next few days. So get a MN before it is too late.
