Everyone saying it's kinda late and that is partially false and partially true. It is true in that you will make very little (like maybe a couple hundred dollars per year per card you use, and we're talking high end cards) compared to the past where it was a lot easier to mine and therefore earn more bitcoin (bitcoin becomes harder and harder to mine over time). However like I said, it's false to say it's late since you DO still make a little bit of money in profit.
