Im fairly heavily invested in bitcoin but would never go ALL in on anything. Too risky to put all your eggs in one basket. Good luck to them though, I strongly believe in bitcoin & theyll most likely become uber rich.
Investing all mean taking a little more risk. I think we should invest such amount of money in bitcoin or in any other investment where we can afford to lose, and should remain such amount of money from where we can take another start. i think it can only be possible if we have a good amount remain after losing the first in business, or we should try to invest money in different business so that we should not lose all the money in one time.
