why not? as he explained it it is only money and he can and will make more in the future. if he is certain that bitcoin is the way to go, then why not. so far he is right price is 25% up since he bought, even with the latest dumps. as fare as the picture goes i do not think it is a big deal and we even do not know if it is true. could be a good deception.
It is still not wise to put all your money on a single investment. It is best to diversify it. If things got worse then he lost all his money. That money is hard to earn back even if you have a good job. If you have a few investments, if one fail the others will cover the loss.
Well maybe op just thinking that if he is going to do that the profit is going to be big. But that is really not a good thing that he is going to spend all of his savings. That is why we are saving so that we are going to have assurance for our future and we can get something if there is an unexpected crisis is going to happen with us.
