The bank spread is high, but the risk is much lower, so it can't be said that the bank is pitted. Banks have no leverage (at least Chinese banks in China have no leverage), so the risk is low. If you are a good foreign exchange trader, you can make money in the bank. If you only know a little about foreign exchange, you won't make trouble in the bank, at least you won't lose too much. I have argued in the bank before, and the difference is more than 14 -20+. Even if you argue for a year, you will lose less than 10%. If you are in the periphery, it is estimated that it will explode in a year. But if you want to make a profit, you won't win much by arguing in the bank. Mainly depends on your profitability. It's good for novice players in the bank. She can not only give you the pleasure of competing for foreign exchange, but also make you lose a lot. And at least more formal and reliable than outside. If it is good, go to the big peripheral platform, but there are also various risks. You should estimate your own profitability.
