The trend everywhere is towards mobile connectivity. In countries like Sudan, only 20% of the country has mobile internet access. That will shift to 70%+ by the end of the decade. This will have a massive impact as hundreds of millions come online.
Bitcoin will play a big role in this. It will give anyone with mobile internet the power to be their own bank. The question is what does that look like? Will they simply use Binance? Or will they use Bitcoin in a self-custodial way?
