Bitcoin as a future currency will maybe happen but I don't think it will because we already have online banking and there is no need for crypto.
Bitcoin as an investing object is just a gamble and it started to be popular because of COVID-19, people were bored and started to gamble from home. If you have some extra money you can invest in it but I would not recommend it.
Bitcoin is one big bubble and we are just waiting for it to pop. It doesn't have any real value and the price is just ridiculous. People never learn no matter how much time it needs to repeat and again people will lose houses and jobs just because they are listening to someone's advices on investing and they bet without understanding.
