is it another btc fork? Or it is independent coin?
It's a fork with a claiming service in which the devs are in control of a large amount of the total supply. They distribute to registered addresses. If you can put 100% trust in the devs this may be a good coin. My advise is exercise extreme caution with BTX.
It is a virtual fork , it can be claimed with btc but has it's own blockchain , so no 100+gb to download. Very fast coin and can handle a lot of transactions.
Devs have been proven to be trusted since april now.
