Yes, they'll still use it. Think of the countries where it's been said to be banned like in China. It's known to the world that the government have banned crypto for so many times and that's why many doesn't like their take on it. And still, even during the ban period, they've done so much on it and yet many citizens that are into crypto were silently continue to farm, trade and accumulate cryptos there. They are afraid of their government because it's a strict one but they have solutions and alternatives on it by simply flying on their nearby countries where it's not allowed to do the transaction and other related things to cryptocurrencies.

I don't think so. The market has already established itself and the degens are there, we the holders and the old investors will simply ignore the policies but we'd hold silently still.
