what is the testnet address to donate coins back to? The donate link didn't do anything for me.

I admit that coin distribution is not a perfect random distribution by person, but I think the important point is that it's mostly random, and not just sitting in the account of the creator, for example. I wanted to emphasize that the math is there to agree on the ledger, and not necessarily create money.

I'm more than happy to add some pop-up notes if people point out mistakes or misleading aspects. I struggled trying to bridge between words that newcomers are familiar with and the Bitcoin world without spending a lot of time on terminology alone, and I think I'm pushing it with 5 minutes as it is. This is why I went with 'accounts' over addresses. Address creation is also completely left out.

thanks very much for the feedback!

I wanted to make a concise explanatory video about Bitcoin, after struggling to find other videos that were both specific about what's really going on, but also not incredibly long. I ended up at 22 minutes...

Would love to get some critical feedback. I definitely simplified some parts (public keys), but I hope I got the intuition and rationale right behind all the aspects of the system.

thanks!
