We are experiencing a great Bull Market run - currently paused near the All-time-highs - so clearly the prices have increased.
UAE is one of richest countries in the world, if there are 72% local users buy Bitcoin, why the price isn't increased?

If you pay attention, you will see how many countries like Bangladesh, Pakistan, and Sri Lanka did not use Bitcoin or Sat currency before, but now many people use it, but it has not yet been legalized.
Even 99% of local users in these countries invest in Bitcoin, I don't think there will be a major change since they're underdeveloped countries and lack of money. They either hold their coins in CEX or they use layer 2, if they use on-chain, the fees might be higher than the amount they want to send.
