the future of bitcoin is very bright because user of bitcoin is increase day by day and every one attracted to bitcoin.
There is no doubt that bitcoin has made itself a very attractive crypto currency for the investors and this attractiveness is only due to high profitability and some other distinctive features like decentralization, privacy, fastest and easiest transactions. People who are now millionaires or billionaires are also a reason of motivation for new comers in this business.
Only few are millionaire of the total users of bitcoin because only few are willing to risk and believe that bitcoin will grow.
It's just lately that when bitcoin breaking it's ATH after ATH where people are attracted to investment but I still believe some of them are weak hands and they will easily panic especially with what happen to the price where it reached 20k and dump close to 50%, that would hurt people who are new and like I said might create panic.
