If you're thinking history repeat itself that the price might crash like few years ago. I don't think it will happen again, btc is more popular now compared before. The number of user and investor has already grown up and keep on growing day by day.
How do you know how many coins there are regular users and how many coins from whales. They can crash the market at any time. Who knows personally the man who became rich due to the fact that kept their coins? Whales know how many coins are mined and they always have the option to keep the price down until they buy the entire volume of free coins.
