There are thousands of options for new kinds of crypto that have not been tried.
Consider this:
1. A crypto that identifies each user so that he gains a good reputation or a bad reputation regarding his transactions and faithfulness in them.
2. Cellphones that are walkie-talkies, something like the original cellphones were, so that there is no central control over the cellphone messaging.
3. Actual transactions remain private.
4. A justice board, like a jury, to make judgments in transaction disputes.
5. As airlines sell tickets through Internet comparisons of prices, let everything be marketed based on the prices of all merchants.
6. Get government out of buying and selling; keep it in areas of justice among people; No more fiat money.
We, the people, can do this.
