Be realistic. Do you believe Bitcoin would help build a cashless society? Was it a Bitcoin goal? I don't think so. Because Bitcoin fees have become higher, and most likely, they will continue. For a long time, transaction fees have become unrealistic. We thought it would become normal after a few days, but it seems like nothing. Its true worls are moving to a cashless future, and many MFS services are helping with that. Bitcoin has become an investment opportunity. If transaction fees become lower, then Bitcoin would keep playing a role in making a cashless world.
I see what you mean. High fees are a problem that need to be solved if developers want people to use BTC as digital cash. Luckily, the Lightning Network (although still experimental) makes our life easier by providing cheaper fees and near-instant settlement times without compromising Bitcoin's security/decentralization. It's a short-term solution for those hesistant to leave their BTC in favor of another cryptocurrency.
With increasing adoption for BTC worldwide, it's very likely it will be used alongside CBDCs in the future. That's assuming it stays decentralized and censorship-resistant. These are uncertain times we're living into, so lets hope for the best.
