It is the hope of every Bitcoin investors that Bitcoin increases and gets better. I believe the government who are still fighting against Bitcoin will one day come to realisation that Bitcoin is a good currency and not a scam. Many critics are now Bitcoin investors, but the question is, what must have triggered them to change minds? The same reason might been seen by those government and they'll change too.
Bitcoin will improve as developers continue to innovate on it. But the beloved cryptocurrency will never reach a point where it will replace existing Fiat currencies. Governments simply won't allow this to happen.
I'm hoping BTC fees decline with subsequent network upgrades (unless the Ordinals craze spirals out of control). The LN is NOT a long-term solution to Bitcoin's problems. Current market volatility, slow confirmation times, and high fees are what's limiting Bitcoin's mainstream adoption. Unless these issues are solved, BTC will remain a store of value forever. Is this what we want?
