a regulated broker is at least safer than trading with un-regulated one as those are pretty much all trading scams and you gonna lose your money. You still need to check a broker license carefully to make sure it's legit ofc.
Aximtrade is regulated by ASIC and their cent account is good for beginner as you don't have to risk alot of money, their spread is also good and low commission fee of $3 per lot.
i dont think it's good to completely ignore trading losses. It's good to learn your mistakes from them but at the same time, you shouldn't let your losses get to your emotion.
as new traders, they lack experience in good risk/fund management. New traders should only commit low budget with the goal to learn and get better at trading then focus on profit later once they improve.
Unregulated brokers are definitely scam brokers so you just gonna loose all your money trading with them, even if you make a profit they won't like you withdraw the money.
i think those 3 points are pretty much what traders should always look for whenever they choose a forex broker. Asides from that may which trading strategy allowed or not to know if their trading plan is suitable.
profit is a pretty good trading motivation for traders, there are always losses but if your wins are more than your losses then you still make profits, no one can win all the time without any trading losses.
a demo account is pretty much a must when you first learn about trading so you can practice. Micro/cent account is when you feel confident and have a strategy that you can stick to so you want to switch from demo to live account trading.
