Question about an investment

Hi, i have a question about an invest a friend of mine did with his boss. His working on a informatic shop and they invested on cryptocurrency that has low value so in future they can gain more money with what they have mined already. My question is if it was a good choice to investe since you cant have a secure port on it and would not anyone question the power consumption of a little informatic shop ?

Cryptocurrencies like bitcoin and such don't really have much to show you the risks of your investment. Like if you were to invest in stocks there is always a general knowledge base to give you information to make your own prediction, but with crypto its almost like a blind gamble. The prices can fluctuate without any predictions on whether it will go up or down. You could end up making a lot of money or losing a lot, and that's the biggest risk.

This probably wasn't very helpful but id also like to learn more about the subject.

I don't think thay are worth minning now. Better to hope on on some else cuurency.

If you're worried about the power consumption then you can always monitor them via a Kill A Watt Electricity Usage Monitor. Also, it'd be a wise move if they used a website called whattomine to calculate which coin will be the most profitable to mine with their current hash and gpu.
