Higher leverage means the broker isn’t properly regulated.
the limit is 1:50 in the US, and 1:30 in the UK, European Union and Australia (those are the proper regulators).
The fact that you have 1:30 (or even 1:50) leverage available on your account doesn’t mean that you have to use it, for all trades.
It’s only really an issue for people with a “gambling approach” to trading. And they’re not profitable traders anyway. To anyone else, this is honestly barely an issue at all.
Unfortunately the world’s full of people who wrongly imagine that “lack of higher leverage” is the main thing stopping them from trading profitably, and it’s also - even more unfortunately - full of brokers who chose to avoid proper regulation so their customers aren’t protected, and do so under the pretense of “being able to offer our customers higher leverage that way.” (Brokers to avoid, obviously!).
These very recent posts (and hundreds of others) explain the point.
