I do not know what such a cooler may be required for. Probably for cooling the mining farm. However, I have never been engaged in mining myself, and I prefer trading. This way of acquiring cryptocurrency is more honest, especially in relation to those people who want to play games with good video cards. I advise you to read about Bitcoin Prime app if you want to start trading. Good luck to you.
Well, I don't think that making money on the internet is the best decision for me. I don't understand people who manage to make a living that way, but it's cool. As for me, gambling is fun, so I just play Slots from time to time without losing money. Anyway, it's great that the internet has so many opportunities, and I believe it's profitable for many people.
