People come and go, They buy and sell, At the end only the hodler wins. This is the market of cryptocurrencies, If you hodl and not panic, You'd win. Did you buy any bitcoin when price dropped to $6,000? If you did then now you are the winner because the price is no longer $6,000. Who wins 15 years from now when the price is above $50,000? The ones who are hodling now until then.
I perfectly agree with this assertion. Price would keep rising and falling in the market due the principles of demand and supply; however the one who has the patience to keep for a considerable length surely gain. Investors who were able to buy and hold till December 2017 had the greatest opportunity of making big time gain from bitcoin; and so it works thereafter.
