Can somebody help please?

I dont find so much to this coin..

I only know that the hardfork was cancelled and then the coin (Bt2) dropped very hard and many people lost their money.

Now i heard from a friend that the segwit update will happen in February.
But i didnt see a source or official site which can confirm this.

Also what I dont know is, if that segwit will really happen: Is that Bt2 coin from bitfinex the original coin, or will there be a new coin?
Is this coin tradeable?

Maybe can comebody help?
I think that is interesting for many people.
