I'm not sure why everyone is saying don't mine, cause even if everything goes wrong u can still sell your cards and get back 60%~ of money. I would strongly advice you to invest into mining, you dont have to mine ETH or BTC, you can mine ZEC aswell, or like 1 week ago electroneum was super good to mine. There is always going to be something to mine and once u get ur ROI, after that its all profit. Personally I like mining more cause it's safer, again its my personal preference. Good luck !
