The only people who will give up on the potentials of bitcoin are those who only see bitcoin as a form of investment and not as a currency. These people most likely do not know or have forgotten that bitcoin was created primarily out of the need for a currency out of the control of the banks and the government. It was created as a currency for the masses.
I however think that the mass adoption of bitcoin in the mainstream world will settle this issue. When bitcoin becomes massively adopted and everybody now accepts bitcoin as a means of payment, then there'll be no other choice than to accept bitcoin as a currency.
What about those miners? Is they wouldn`t see potential to bitcoin? The factor that you bought bitcoin or supports it, you consider it to have a potential. If there could be a massive adoption, there are two factors also we can consider. Either it bring the positivity to the price or it would be regulated by the government. Probably, government does not want to exist a coin that they will not be used in terms of corruption. Well, in all what you said. I agree to that, being investor and supporter of bitcoin can help it to become the mainstream.
