Realistically I have never traded on Gold or silver because I do not focus on them, and as you said would mind mentioning the exchange where it would be that easier for someone to trade them or does Binance exchange do list them on their pairs so that one would possibly them to trade. I mostly do love trading BTC USDT and whenever I noticed the market is dropping I wouldn't mind having back usdt till I have observed that the market has actually dropped to point that interest me before I could buy back Bitcoin.
Is smart to experiment new trading assets that you have not tried before, I cal it new asset cause it is your first time if you have to trade with them first time but you gotta be very careful cause gold volatility is not like what you have with BTC USD pairs you have been trading with.
INot to confine you to your familiar pairs but If I could, I will advice you keep to what has been profiting for you all this times. Combining cryptocurrency trading and precious metal trading can be very demanding than just focusing on crypto trading alone.
Getting to find something that is profiting you is not easy and most people end up with mistakes when they do that, and that's why it's not really that much of a simple task to make some money with all of this, because even if you do figure out a strategy and a pair where you are making money, that could be valid for a day or a week and then it could change and suddenly become not that much profitable.
This is why it would be making some sense for a lot of people to keep trying because depending on the pair and on the market situation the strategies needs to change and for that reason there is no way that you could make a lot of money with a single one, you have to make sure that you are handling it very well.
