A mining farm does not mine bitcoins
This may come as news to newcomers, but it is nevertheless a fact - on a farm assembled from video cards you will not mine bitcoins.
What does this mean? It means that indirectly you don't care what bitcoin's price is or how high it is, as long as the coin you are digging is at the bottom. Of course there is some correlation, and bitcoin usually pulls altcoins with it, but not as fast as we would like it to be, and it would be better not to have this correlation. Because when bitcoin falls, then altcoins fall to paltry values and sometimes can not rise up, unlike the first tier of coins.
Bitcoin has investor support, it has popularity, it has a "first" position, but the coins that you will dig (and you will, simply because you have no choice) will only have uncertainty and distrust of the project.
Some tokens cannot be mined, there are many algorithms you will have to learn, of the basic division these are:
POW (Proof of Work) - in this case, miners are needed to keep the network running
POS (Proof of Stake) - in this case you just buy coins for a wallet, service or node and "stack" them - freeze them, so you "mine" without video cards.
And if it's a very complicated process for you I recommend to use Internet and find out what to mine asic
