I truly think only 50 million peoples are aware about Bitcoin or cryptocurrency. News is popping everyday related to bitcoins and crypto, new people's are learning and attracted towards it and as a result of this peoples invest in bitcoins and more peoples means more price up, 50 million to 100 million customers definitely means price could easily reach $5000 but I don't think it could hit $50000 that's a useless prediction.
I agree that there's not a huge percentage of the population that knows about bitcoin and many that have heard of it couldn't tell you what it is or what it does.
It will take time for bitcoin to go mainstream and at that point, the value could be much higher than it is right now.
