When buying crypcurrency, Buffett said, "You do not invest when you do it. You are speculating. There is nothing wrong with that. If you want to bet others will come and pay more money in the near future, it's a kind of game. But that is not investment. " Are we participating in a game?
everyone has a different argument and they a free to say it. i'm sure they have a reason for that. for me, bitcoin is like a business sometimes we get a profit and also sometimes we lose our money after investment. it's normal i think, no one business can make you profit always, all of them have a risk. i see that bitcoin price always increase every year, and always have a huge support from his user. so i think bitcoin is good for investment.
