Honestly, this is still what I keep until right now, I always use money that I will not use for daily needs or other needs, I mean maybe free money to invest. Additionally, I am also always investing money only in the amount that I can afford.
Although that kind of finance and other fiat problems may happen, I am still not ready yet if I should lose money more than I can afford. So, investing wisely is better for me. AT least, I have enough investment but without over risking my money and my life.
But, I know that everyone also has different opinions and considerations. As long as you can afford it and are ready for whatever will happen with the investment, it may not be a matter.
