#2 should really be replaced with something along the lines of, If you dont have ownership of your private keys, you dont own Bitcoin.
Storing coins on exchanges should never be advised.
Also, it is impossible to keep all these commandments.
If I follow #3 (sell high), then I break and #10 (HODL), and vice versa.
And #7 has nothing to do with Bitcoin! Why would you recommend that someone diversify into scams? If they are going to diversify, then they should think about precious metals or other commodities, or securities (stocks), or bonds. Moving form Bitcoin to other cryptocurrencies is NOT diversification.
