Well it should be worth more. But you want to have money coming into your bank account, well you can't just hold. Thus i mean for someone to cash out consistent profits. So if thats the case, isn't usd more important?
No, because you want to cash out as little as needed, the rest stays invested. Money in your bank account doesn't accumulate, so basically you're losing potential profit there.
Daytrading doesn't mean, invest us$ into something, hopefully make profit, and then take all us$ out again. It's building up a portfolio and let that grow by making swing trades on a day to day basis.
