Aloha and Welcome! :wavey:
There's no rush if you want to jump into online pin trading. I understand that it's difficult living away from parks and there are so many pretty, shiny pieces of metal you'd like to own ... but you're afraid of making a mistake (overtrading, making a bad trade, getting scammed, etc).
I would just take it slowly, at a pace you find comfortable, and always use common sense: remember that if something seems too good to be true, it probably is. Don't ever make a trade/sale unless you're 100% comfortable with it, don't let anyone pressure you into making a trade/sale - and don't be afraid to ask questions along the way. Remember that if you're meant to own a pin, it'll find its way to your pin bag (either through trade or purchase) eventually.
I hope this helps, at least for general advice on getting started. If you have any questions, don't hesitate to ask them. I'm sure that someone (or several someones) will be more than happy to answer them for you. 🙂
