Yeah I agree with you for daily trading BTC/USDT or BTC/eth really works. You can either buy long or short it means you don't depend on the scenario of making the coin going high since you can bet into low direction. It only depends on how your charting and marking analysis run.
I'm against daily trading, either putting you all day in trade. Even stopping limit loss can't help you with daily trading in this cryptocurrency situation.
If you are not good anticipating the market movement day trade won't be your friend, as volatilities will hurt you from time to time.
When the market is getting higher and higher, your daily trade can't save money. Yesterday the BTC price was 9.1k, but today you have to buy Bitcoin for 9.4 USD. Hope you understand my calculation.
The very reason you need to learn about calculations and anticipations, once you understand everything, it won't be hard to
expect what will be your next position and how long will it takes to execute.
Make investments weekly if price dumps don't make any investment or can make low investments.
Everything that into your knowledge will let you to position yourself, if you see that dumped is coming you can place your
order to a much lower price, wait till it's fills up then wait for another cycle before selling it back.
