Can mining be considered a long-term investment? If Yes then drop your plan or reason why and if it's no don't hesitate to share why
The main mining expense is paying electricity bills.
Other expenses are rent (if you don't use your premises) and security.
When we talk about investments, we must know your capabilities and investment amounts.
For example, you can figure out which is better if you buy $ 20,000 worth of cryptocurrency now or buy video cards for mining in your garage and mine for 3 years.
The cost of electricity is, for example, 6 cents per kilowatt.
If you bought Ethereum for $ 150 more than a year ago, you would already have made a lot more than miners.
