I am just surprised at the fact how come a senior member becomes a doomster of Bitcoin! After viewing you post history, I found you have involved a lot in the bitcoin stock investing. Probably you made some loss so you are despaired of it. In crypto world there are a lot of scams, fraudulence etc. It is fully understood that some ppl encounter it and leave.
I've lost about 1 BTC in securities, yes. Annoying, but hardly a big deal. Lost a little bit and learned my lesson. However, that is not the reason that I am doubtful of bitcoin's future.
