Only buy bitcoin with money you can't afford to lose is on the verge of reckless. It's something I see a bit from people who have enough of a stack that weathering a bear market isn't as painful to as the upside they get by hodling through it constantly thanks to the upward trend.

If you rely on constant liquidity of most of your money, that's just not viable.

It's a goal to be worked toward for sure, but it's hard to buy more if you've starved, or lost your job after you lost your home because your rent money just reduced by 80%. Understanding your tolerance for volatility is a must.
