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.
I would not sell my properties for something that is not reliable. You might get bankrupt if the market falls and you end up being cashless and car less. It is good to take risk but we should be able to estimate if you can take that risk to gain.
