And this right here is the problem, and the coming downfall of our race. People expect to put no effort in to understand something new. This is part of why we have QAnon, anti-vaxxers, etc. Because it's easy to do nothing. It's easy to read the interesting click-bait on how Bitcoin was used to steal millions, etc. It's easy to hate, it's easy to bash. It's a form of release - I get it.
And no I cannot explain blockchain in less than 100 words. If that's what you need, then you deserve to stay poor and/or keep complaining about politics and other issues not going your way. Now could I explain to how to use one in less than 100 words? Sure.
It's not about you right now. It's not about improving your life right this very second. Though I'll take the bait anyway for right now: your crypto is not tied to your identity. So if your ID is flat out stolen, and some drains your banks, brokerages, etc... your crypto - assuming you are properly storing it on something like a hardware wallet, is safe. You can do this with physical gold too, but I'd rather have something that's liquid like crypto. Additionally physical gold can be stolen too... but a private key can be memorized. Is it the improvement you want or care about right now? Probably not, but for me it's worth having an ultimate failsafe.
Now since I answered your question I expect one in return: what is crypto doing that is hurting your life? Causing GPU shortages so you can't play the latest useless game at 200fps?
