I would also recommend going micro if you're not rich. I'm trading with up to a $1000 sometimes, when i'm not withdrawing for a few weeks, and micro still feels better. There's also the Ultra Low micro if that's someones jam, if you have positions that are not closing for days straight.
The education stuff people write about, its not that great. I think its basic. I also read the blog on Medium that XM has, its also pretty generic (although some golden nuggets of info here and there). The real beauty is in trading experience and fluidness of it all. Order execs, payments processing, etc.
