Mentally Challenged

I have a new huge bank of €100. I've figured out that if I make 25% each day (and take commission into account) my bank should be €3788.67 by the end of the month. Because I'm a modest guy (very, very, very modest actually) I will settle for 3k. (2k would be pretty cool too btw. Or 1k...)

Good luck, myself.

PS All tips are welcome.

(Well, not ALL tips, only good ones of course...)
