so you guys trading with btc - do you not trade into USDT when all is going down? So is it not better to focus on the stable coin as base currency which will of course increase your BTC over time?
It's an option but not
"always".
Since you are confused, you might want to test what will be the outcome if you did both.
You might saw others gaining advantage on that strategy however, that's not always the case to all. Goodluck.
