People are invested in bitcoin in many ways.
They see good reasons to stick with it and most of them are thinking long term.
Things crash from time to time, it doesnt mean they are dead.
And besides that profit isn't the main focus for most of the old dogs of bitcoin.
You are totally right! People who have the passion to do and continue doing Bitcoin must have the passion and not easily believe on what other negative people think about Bitcoin. People must choose the right path to take and right campaign to choose. People must believe that in the right time Bitcoin's value will no longer low and will be successful in the near future. Its not the end it just the beginning od Bitcoins journey.
