Mining, still worth it?

It depends, but is easy to do the math, just make an excel sheet, put the cost of the gpu's or asics hardware, electricity cost, monthly revenue, and you will have the answer. For someone with free or lowcost electricity will be more profitable than someone that is on a country where electricity is expensive, taxes are also something to take in account.

We need to take in account another key factor, the price of the coins, and no one knows what will happen in the future, maybe you mine, you hold the mined coins and these coins will have a value of 5x or 300x in one year from now o maybe the value will be something close to zero, who knows.

Until now the price of bitcoins just went up, and up, and up, but now bitcoin and other coins are facing some key decissions, first is the regulation, on some countries transactions in crypto are banned, in other places are accepted.

Still worth it?, there's no a clear answer, you need to know like any other investment if you can get an high return you will also need to accept high risk.
