I have always been interested in mining cryptocurrency in a very long time and my biggest obstacle has always been the financial resources to purchase mining rigs and electricity required however remaining crypto-currencies became almost impossible for me because of the high cost involved and very low profit margin so I am pumped to ask that with the recent pumps in crypto prices and everything going to the moon is it profitable to mine Bitcoin in 2021 or any other altcoins please let me know.
Yes and no, if you are going to mine a coin with your low hash rate rig then you are going to make less than what you are paying for your electricity so mining need huge capital so that you can build multiple rigs to mine something which is valuable and also it depends on which coin you choose to mine. If you select ethereum then it is not going to be profitable for sure.
