There are only one coin named: ViteX coin, also named VX. I think what you are talking is the same coin.
I'm sorry. I did searched it again and found out its VITE token and another VX coin. That's two. I found out here -
https://bitcointalk.org/index.php?topic=5170304.0which they distribute VITE tokens to bounty hunters and then they also have the native coin which is the VX as said here in this
thread.Are they two different projects or two different coins for one exchange project?
They are two different coins for one exchange, ViteX coin or VX coin is used for dividends on the exchange while Vite coin is used for empowering the exchange such as coin listing fee and can be used for voting to generate a new Vite coin or staking to generate a new VX coin.
