My friend decided to sell his car and invest all the money in Bitcoin as some people predict that 1 BTC will reach 500 000$ till the end of 2019.
He totally believes in it and tells that then he could buy not only a new car but a flat also.
Does it really worth it? He uses his car for his work and now he wouldn't be able to do this anymore as he thinks there's no need to work anymore.
It can be a good investition. But it is to risky. Nobody know when bitcoin will grow. Your friend cannot work without his car and it is a big problem.
Actually, I do not think that the buddy made something very wrong. Yes, this step was might a bit risky but listen, people: if he succeeds, he can buy two or three cars as he had before, and this is true!
