Bitcoin-Satoshi-Nakamoto, the original still running with less than 0.01 US cents. The other one called Bitcoin-Segwit (others called it Bitcoin Core but that is a misnomer), is different with the signatures moved to another database.

The easiest way to educate others is let them buy BOTH. Then let them try on a wallet, then try one send and one receive transaction.

That's how it works, in real life.

Those who won't accept this, you can conclude they simply are obsessed instead not on the usage but on banking it becomes high value in a year or two.
