Mining farm + solar energy project

[n0x90]

hello everyone, first of all nice to meet you, I'm new to the forum.

I have been interested in this world for a long time and now I got the idea of ​​starting a small mining farm powered by solar energy.

according to you which algorithms should I study the mining farm? I was thinking of 144_5

what do you think would be the best ways to make this long-term situation profitable without risking having to throw all the GPUs in a few months because they are obsolete?

I am open to any idea and any advice

thanks in advance and good day to all
