Do you always missed the right time to sell or buy bitcoin?
Nope i don't missed the chance to sell my bitcoin from exchanger i always set automatically price of bitcoin where once the price i set hit it there will people will grab that and then had that profit exchange into fiat currency and use for my personal needs.
i do not think that there will such a perfect person who can claim that he never missed the right time to buy or sell bitcoin. for me although for some time i catch the right time to trade but other time i also missed good time to buy or sell bitcoin in right time.
