So, yes, bitcoin fork bitcoin gold are finished. Now Bitcoin supposed to be lower than now. -500$ it's just beginning in my opinion soon it can be decreased to 5000$
no , 5,500 are a good buy if you can do it then just do it by now before you left behind.
the future prospects of bitcoin are still far away from reached, we can do a lot of things with bitcoin , and people will come to invest and use bitcoin sooner or later , the last few months breakthrough are enough to show bitcoin existence off the world , next achievement should be at $10,000 , don't regret it later , just do buy it now.
