I would say that you can do both, that is if you have the necessary funds to do so. Investing in mining equipment can mean a big money so the next choice would be buying Bitcoin especially that it is in the big dip right now...you can buy it cheap and then experience some profits when it would be back surging in soon. You can save money to get into mining business so it depends to you really which can make you happy and hopefully profitable in the long run. Good luck!
