Give up bitcoin's technical development? I still see bitcoin's source code is updated regularly.
We need to see that bitcoin is hard to innovate, but I believe it will soon adopt something to be the top currency as people expect it to be paid daily.
I only noticed that bitcoin investors were impatient when bitcoin dropped and they quickly left. As always, there are sellers, there will be buyers.
Bitcoin is at a pretty good price point and is stable for many days. I don't think bitcoin will depreciate in the future.
