It would depend on the person. For me personally it has allowed me to shift to a working from home approach, and saving a lot of money on transport. I am also spending more time with my family which i like.
I know that 212Trading gives free stock if you sign up a friend, but i havent tried it yet to see how good the offer is.
Otherwise, they are basically free to use, which is cool. I have used it mostly to buy oil, since it crashed hard.
