earning 3btc in 1month then loosing 4btc at 1month too

Actually, you're already deficit for a 1 btc and maybe if he another people will say "you will get experienced and knowledge from your losing" you don't need for believing with that. I can assume if you're trading with more than 1 btc is related to high amount and then maybe you're already having a lot of experience and knowledge but in this time you're saying get a deficit for your amount and that is very bad... maybe there are some of your ways is get a wrong for managing your money in trading or missing for taking a good moment for buying and selling.
