You missed the point.

Popularity =/= Performance.

You can be well known and still be terrible at doing certain things. Just because Bitcoin is far more popular than Monero does not mean that it is better than XMR. That is an incredibly childish way of looking at things.

"Changing lives" is in the short-term. You need to start looking at the long-term as well, especially since so many countries have been looking into having BTC strategic reserves, leading to the centralization of BTC, as well as the rise of companies like Chainanalysis that can track transactions so easily. You're better off just using your credit card if you choose BTC.
