If there are effects, it would be local effects, in your nation first. Then, if your nation has a big role and effect, it will in turn affect the global market. I don't know much about your nation but it seems that your nation does not have big communities for Bitcoin & crypto.
It is not about local or international effect, Pakistan is not a country like USA or China that have the economic power, if cryptocurrencies is legalized in China today, the price of cryptocurrencies will increase just because of how China is, also if bitcoin is banned in USA today, the price of each coins will reduce.
But in countries like Pakistan, what you need to know is about their interest in cryptocurrencies, also about the recent crypto trading volume in the country. Cryptocurrencies were banned in country like Nigeria, but no reduction in trading volume in the country, other countries do not even care, and crypto prices were not that affect at all.
Are Pakistanis still trading after the ban should be the question, if they are trading just like Nigeria are still trading crypto after the ban, the price may not really be affected immediately. Also with how the country is, I do not think if crypto are legalized in the country will result to any significant effect on bitcoin price.
I remembered when India legalized crypto, not long that South Korea also legalized it within the same week, but crypto prices were not affected positively at the time, which can be a sign that the citizens were even trading cryptocurrencies during the ban.
