i had played forex and all my money turned into lost ,because i left open orders when i went sleep ,those made me avoid any kind of gambling sites,controled by others, its amazing the coin doesnt moove when market is open and when we go sleep the markets wake up and dump or pump enought to catch some orders...
forex is not a game
, how do you play foex 
?I think he meant that he lost money trading or lost gambling with sites like secondstrade.
i left my job ,then i found easyforex and made some deposit i had won around 120 euros in 3 hours,i had invested all money into 3 positions one were eur\usd and usd \jpy and yes i learned the hard way i dint know what were forex i were newbie.The same thing happen with exchanges of altcoins left some order open may result into a loss as market mooves 24hours a week soo the advice is to avoid any open order before sleep ,but if you left it choose some exchange that allow you to stop loss at x value.
