It would be really terrible and problematic for you in the future if you think that Bitcoin has no risk at all, yes it's true that the risk attached to Bitcoin is small when talking of other investment, but do not go all in, on your investment in Bitcoin because nothing is certain, so that if Bitcoin doesn't live to your expectations in the future, you wouldn't have to contemplate on committing suicide, that is why it is adviced to invest only what you can afford to lose.
Depression and suicide is real buddy, don't just get into that shitty situation.
Bitcoin is a risk worth taking and I'm very glad that you acknowledge that, you're right to an extent which is why it's best done with the discretionary funds and not going all in I don't even think one would be able to stay long without tampering with their portfolio if they go all in with their income cause they'll have basic needs and other important problems to solve but with the discretionary funds they'll be on a safer side if anything happen in future. But then Bitcoin has given us hope that the future is bright with it and that's what keep every investor motivated to buy and Hodl for long-term. Well it's lived beyond several critics expectations and we're hoping that it would continue to do that for many more years.
