bitcoin will split into two chains, one that will have segwit activated, the other one will now. So there you go, there will be a version with segwit live on August 1. You just have to make sure that your exchange, or your wallet supports segwit before the transition and your coins will be bitcoin with segwit. Make sure you are on the right side when this come because one coin will die. Also I suggest you to diversity your investment and buy litecoin, it already has segwit, so if bitcoin activates segwit succesfully you win, and if not litecoin already has segwit you will win there as well.
Let say if I choose the correct one, will bitcoin value will back increase like golden days like ever before ?
Actually I'm also worried and my friend also yelling on me and asking my opinion about SEGWIT things.
Ofcourse I need to calm them and myself for preventing any bad action
I'm afraid the picture that is glimpsed is not very good, There are too many things that are converging on that event, At this rate and considering the days that are missing the price can be collapsed until the $1000 or less maybe but that is a mere assumption, And perhaps the worst for many peoples while the price continues in free fall neither alt can be considered safe option, The risk of splits is too much even to ensure that the price will recover soon.
