What you mention about the emotional impact is very true. Risky assets like cryptocurrencies can bring great joy, but also a lot of anxiety if we're not prepared for the crash. As you rightly say, we're not just investing money, but also our peace of mind. Learning to live with that volatility is the real challenge for the modern investor.
For the moment, I'm not facing these kinds of decisions; I have enough to worry about just living in a country where we face challenges in how to get through each day. Best regards.
