Totally agree, In a quite high-risk investment like Bitcoin and Stock, if someone ask me this kind of question my answer is most of the time, 'Invest with the amount of money you can afford to lose'. Other than that, investing with the money you can afford to lose, make you less worries when your portfolio is failing, we wouldn't be anxious to sell the asset, if we currently got unclaimed loss, so we can continue to accumulate and grow our portfolio.
Bitcoin is a high risk investment, it not quite high-risk investment.
