Hello it is much better if you buy them from the market as mining them will take you a lot of time especially if you have to spend a nice stash of money for that.
Suggest you to put the money you wanted to spend and buy the coins directly.
Cheers.
Mining is fun, but highly unprofitable. If you don't already own the equipment, it'll definitely cost too much. I wish I had not started to mine, I've wasted a lot of money doing it, but I did enjoy learning. Mine on whatever you have already so as to learn and have fun, but buy coins if you want coins.
