Bitcoin is the only coin to hold for a long time to earn from cryptocurrency. A person can earn good amount from Bitcoin if he invests for a long time. There were many tokens in the past that are now dead, and investors who invested in those tokens lost a lot of money. Most shitcoins pump for a short period of time, but later those coins turn into scams, once those coins die they have no value. That's why if you want to make a video, you must think about it. If we invest for the purpose of making a profit, we can never invest in any other coin except Bitcoin. Investing in Bitcoin alone is possible to make a profit, and will always incur losses and lose money.
