Check out this site for profitability, but if I were you I'd do my research on reddit, twitter, and on other forums. Make sure you know what you're getting into, but with the fork you might as well be throwing away cash for an over priced brick tbh....

The fork is a complicated event. The questions are:
1) when will the form happen FOR REAL?
2) how many coins, after monero will fork?
3) How many coins will not?
These 3 crytical variables are the ones that should be taken in consideration when buying the Giant N or the Halogen x1/x2. They could be and remain money machines or be just not so good looking doorstoppers.
Anyone has an answer to my previous 3 questions?
