it is always recommended that never invest what you can't afford to lose completely, it doesn't mean that losing it is not felt.
This definitely shouldn't be a surprise especially when been involve in Crypto because it's a 50-50 scenario either you gain or lose but the most important thing is to take the right decision and invest wisely rather than adding greed to it because of massive benefits that can lead to a huge lose.
play the cards right and perhaps it is 60-40 :)
