"I would suspect, down the road, that a number of central banks will have digital currency," he said. "When there is a digital currency available, other than the underground economy, it’s not clear why people would use bitcoin."
Of course quite a lot of countries and Central Banks will launch their own CBDC's, but the misconception there is that it's going to hamper Bitcoin usage, initially people had that thought when talks on CBDC's become popular, but it's obvious clear now that CBDC's are simply going to be digital Fiat, that'll be centralized and controlled by the central banks.
Having said that, the Bitcoin community will no doubt continue to grow, it already is, institutional Investors now believe in the network, so people and more people will continue to use Bitcoin, it guarantees control, freedom, it's a hedge, a currency and other whatnots, Bitcoin will only continue to get more popular and not the other way round.
