PoS is the best alternative for the future of cryptocurrencies. Given the fact that there are already problems with providing electricity to the country, in the future this problem will only worsen and for the development of cryptocurrencies it can become a serious problem. And in general, I'm for the environmentally friendly types of consensus that won't deplete the finite reserves of our planet.
It is absolutely correct, even if it comes today from electricity, I also think that the proposed option with POS is much more profitable, despite the fact that the banking sector spends much more money on electricity.
