There are SO many, it's very difficult to keep track. But my advice to people is to study the basics if you haven't already. The things devised over ten years ago are the things that have staying power anyway. Also, study the laws of your country, and the history of money.

And if you don't really understand lightning yet, learn as much as you can.

After that, #cashu #nutstash #fedimint #ecash are going to change the world.
