that coin has masternode feature ? or something like that ?
No. It is not a Proof of Stake coin.
Please check out a few links to get you started:
https://community.xtrabytes.global/faq/https://community.xtrabytes.global/threads/everything-you-might-want-to-know-about-xtrabytes.330/As far as nodes . . . .
STATIC (Services Transactions and Trusted-in-Control) nodes form the backbone of the XTRABYTES network and play a crucial role in the consensus, security, and governance of the platform. STATIC node owners receive transaction fees and service fees for the DApp modules they opt-in to host. Security and PoSign consensus are insured using state-of-the-art encryption hash technology, requiring that every block is signed by the nodes.
Node owners receive a share of tx fees, and will receive additional income from modules that they host in the future, and also share node registration fees . . just a few ways that having a STATIC will grant you passive income. Much more complex and unique than a typical Masternode coin.
how much coins is needed ?
The first very important factor to realize is that a STATIC node is a deposit, not a cost. The fees are a cost but the actual deposit is yours and you will get it back if you ever decide to break your node.
A level 1 STATIC node deposit consists of 500,000 XBY or 330,000 XBY plus 170,000 XFUEL
A level 2 STATIC node deposit consists of 250,000 XBY or 170,000 XBY plus 80,000 XFUEL
A level 3 STATIC node deposit consists of 125,000 XBY or 85,000 XBY plus 40,000 XFUEL
