It's not a problem if you make up for it in the 5 weeks you are home!
The program is structured step-by-step, so you can progress at your own pace. So it's no problem to join.
Bankroll - the bigger the better!
For Micro 6-max you don't need a big BR, some guys start with 50 EUR, and make a few thousand after a few months, like these guys for example:
Our 6-max student "justplayff" joined BPC in September with 50 EUR in his pocket and a willingness to learn, and grind.
He started at the bottom, playing the Micros.
Currently he is over 4000 EUR up, playing NL50, and planning his shots for NL100.
Check out his blog here: LINK.
Or this guy:
Our 6-max Micro student from Serbia, Lateralus, is over the thirst third of the Micro program, after having joined a few months ago.
He made close to 3500 EUR already, over 5x what his starting bankroll was.
