Hey Andrew,
Welcome to the Forum! Yes, the new regulations are a bit tide and especially when we were used to trading last year with bigger leverage, now it seems a bit more difficult but it is not. These restrictions were placed to limit the losses in the traders. Also, the brokers started to benefit less, not as they used to be.
Now trading with lower leverage is really not an issue. You will have a smaller risk indeed and profit can always be achieved.
Give it a try on a Demo account and see how much you would fit trading from let’s say 2k account.
As a beginner trader try not to think so much about the leverage and the potential profits you can do but about the strategies you will use. Try to learn and master the system you plan to use. Once you are good at it, the leverage won’t be really an issue. But if you do not have a profitable system that you can apply, everything will be an issue :)
