i had an account with oanda.
i took 100 dollars (and with a few deposits up to $10,000), got it up to 80,000 by december.
by february of the following year (2 months later), i was down to 1000.
luckily i took out $35,000 and renovated our upstairs.
the only reason i did forex (as i knew it was a crapshoot the whole time) was because i didn't have $25,000 to maintain a daytrading account.
but as of september last year, i'm good to go in stocks again and just check up on my shitty oanda account once a month for shits and giggles.
stocks are much more "predictable" (using the term loosely), but forex is just crap.
for people without money to go into stocks, i'd recommend options or even trading the emini , if you really want to stare at a screen for 24 hours a day.
