BTC fees are skyrocketing to the moon in what some are calling a crisis. Bitcoin has become completely un-useable as an actual functional currency and many are switching to alternatives such as Solana for speed or Monero for privacy.
Unusable just because of an increase in transaction fees, that most be a joke. What Bitcoin is experiencing now can't be compared with Ethereum increase in fees when it happened yet it was still been used so what makes you think people will stop using Bitcoin. We have lightening network that can be used to avoid paying this high fees. Things will go back to normal very soon no need to panicking.
Business owners accepting Bitcoin can switch to using of the lightning network for faster transaction until the congestion get resolved. Solana or any other altcoins you're promoting won't and can't replace Bitcoin. Solana is a dead projects and should be avoided.
