This can be a difficult situation. While it's good to be open-minded and constantly educating oneself, it's important to remember that Bitcoin is the gold standard when it comes to cryptocurrencies.

In my opinion, it's always better to stick with established cryptocurrencies that have a proven track record and an experienced development team. Since Bitcoin is the most widely used and accepted cryptocurrency, it's natural to prioritize its adoption over others.

As for the request to accept another coin, it's important to be respectful but firm in your approach. You might politely explain that Bitcoin is the main focus but that you will continue to monitor other coins closely and keep an open mind. It's also worth noting that Bitcoin's open-source nature allows other coins to learn and borrow from its successes, making it an important pillar of the entire cryptocurrency ecosystem.
