and by the way, when you trade a fucking $200.01 and pay $0.01 more as fee, of course a $0.01 will change your life right ? and if you do that 100 time a month this would sum up to $1 in total, this will get you broke!!!
This is wrong because there is automated trading that does a high volume of trades in a short period of time. Even if you don't do this yourself, if your orders are traded against by algorithms you may get many, many executions. There is no reason to assume 100 trades in a month is a lot. You could get 100 trades in a minute.
