At this point, I'm giving up on mining altogether. After all the hours of research that I have done, mining just seems to be an arms race of who can get the biggest and baddest hardware. It just doesn't seem sustainable in the long-term.
However, what I have been interested in is Bitcoin trading. It seems pretty easy and doesn't require you to invest a lot of money. I made a couple bucks today when the price of Bitcoin went to $252.
Trading is not as easy as it seems like. 220-240 circle has just been broken. Good Luck though

I'll have to do more research. I don't have much experience in investing but it seems like the price of Bitcoin is so volatile that its easy to buy low and sell high-ish. Anyway, trading seems a hell of a lot more reliable than mining.
