Re: [ANN] GOBYTE [GBX] - Masternodes, PoW, Secure, ASIC Resistance, & Decentralized|

i should have 1000 coin to have the XXX ROI ? or can use small amount of the coin ?

ROI = Return of Investment.
1 GoByte Masternode is 1000 GBX.
You will get back those 1000GBX from the MN payments in ~ 18 days. This is the ROI.

OK great i had 50 Coin how i put it in a masternode ?

You need 1000 coins for a masternode.
