Bitcoin will continue to grow as more and more because every people will think bitcoin is a very good investment. At least it's all our hope
That's what we have seen in last 7 years. The journey of bitcoin has highlighted it's potential and a clear picture of the future. Currently not even 0.5% of world's population is using bitcoin but most of them are using fiat currencies. Just imagine what could happen if we could grab at least 5% share of world's population in bitcoin user base? I don't have any doubt in my mind that the price is going to rise.
People now are getting smarter and embracing the technology of our world and for sure we already surpass at least 10% of our world population and they area already using cryptocurrencies for trading or such a good investment for their portfolio and if this kind of adoption will continue then it will be a good future for the early adopters because the price of their coin will be more expensive in the future.
10% is very optimistic figure. I want someone to prove me wrong but to be honest I don't think that much of people are using crypto currencies at the moment. I am not including the people who have just heard about bitcoin or crypto currencies and not using it. 10% of 7 billion population is a impressive milestone to reach but we are not there yet. However if we continue to grow with the same speed then I don't think that is is far away from us.
