some people say a small account like 4k 0r 1k will definitely blow up but frequently we heard some people with big account blown up too. the conclusion is: the success of trading is not decided by the account size. some people say trading Edge is the key toward trading success, but we frequently heard those with top gun skills fail too. so trading success is not decided by trading edge either if you have a small account 3k, you can divide it into 1500 pieces, each time, you just bet 1 piece, it is possible, buy one cent option plus tiny commision (normally will not exceed 1bucks). you need 1500 trades to blow up 3k account if all are losers, that sounds impossible but if you have a big account 1m, you do not divide it, all in a position, you may blow up the account in one time so what decide the success?
