That's something only you can answer. We don't know your "vibes". Going short is often advised against when the customer/reader is not familiar with financial markets (financially illiterate, newbie). Once you know what you're doing you can use both sides: markets going up, and markets going down.
It is not. Shorting is dangerous when - the market is on the uptrend and you short it - the market is trendless and you short it
It’s much easier to make money in an inflating market where new money is coming in. It’s a lot harder to make money when you are fighting to divvy up a set pot.
The traders in this forum know how to trade up down and sideways to make money. for average people, shorting is more dangerous because if you sell something short at $20 and it rockets to $100 you’re down $80/contract on margin and your portfolio is liquidated. If you buy the stock at $20, the most you can lose is $20/contract, no margin call.
Let's say you shorted BTC at 5K... See? If you actually trade it (in and out) it is not more dangerous, but if you have a bias and doesn't want to give it up against the trend, you can lose more than 100%.
You can't, but you could use some kind of price crossing over the SMA or the 50 and 200 cross. That would keep you in the trend.
