So, invest as much as you feel you can afford to invest from the depths of your heart? :P I just checked my accounts yesterday. I had put 60% of my savings into crypto in the worst possible time (at the bull run). Oh, my, I lost so much! I hadn't checked them for 4 months, and I'll just leave them there in case some magical crypto fairy decides to pump cryptocurrencies back up, lol.

For now, I'm here on Steem, not investing money. I mean, I have more than I had when I invested (I put $150 into crypto and now have around $650 worth of Steem).

At a certain point, though, I had generated over 600% profit from my initial investment. I was so happy! But I wasn't ready to sell because it was all the money I had. I have to teach myself to diversify once things hit ATH, put some back in USDT and check the markets more often.

I can't do anything right now because everything is in all-time lows. :( I think I shouldn't have invested so much money. If I had bought just $50 but managed them correctly, I'd still have tons more than I have now. :P But I couldn't keep up with the despair of the bear runs.

So I think you're right on point with this video. We should be able to take it all clear-headed and not invest with heart-wrenching suffering every time we lose a little bit of value.
