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.
if you want to mining Bitcoin then you need a bigger capital than Ethereum, because mining Bitcoin can only use ASIC and the price is very expensive, but if you want to mining Ethereum then you only need VGA (minimum 6gb) and if the price of cryptocurrency go down (bear run), then you can sell your VGA, because there are still many people who are interested in buying a used VGA and VGA is not only used to mining Ethereum, while ASIC can only be used to mining Bitcoin and besides that the electricity used to mining Bitcoin is greater than mining Ethereum.
