Diversification of assets is necessary to stay safe in investment. Currently Bitcoin is considered a digital gold. If someone invests in Bitcoin for a long time, then the chances of profit are very high. Although gold is able to maintain the value of assets, the return on investment here is very low, but if Bitcoin is held for a long time, it is possible to get several times more than gold. Considering the risk, the investor can arrange the portfolio according to his choice.
Bitcoin price has grown from zero dollar to current price of 115k in almost 15 years, no asset has grown so high in such duration. Gold is considered as safe haven asset for centuries and it's current market cap is very large compared to Bitcoin. But as I said Bitcoin has edge over gold and other asset of investment because of it's price history, limited supply and growing demand among individual as well as in institutions. It's also very important to understand that Bitcoin is good only if you are planning to invest in it for 5 to 10 years otherwise it won't give you good profit.
