If you have enough time, you can trade with the player. If you are an office worker or the time is not enough, you can trade through online transactions and look for suppliers who specialize in game currency. Generally, their transactions are transparent. You can also sell your spare game equipment to the merchant, which is very convenient.
I often trade on the mmoah website, because this is a comprehensive game website, not only provides POE Trade service, other games are also possible, and the transaction speed is also amazing, I have been trading on this website for 3 years. Personal feeling, security is still very secure.
If you are interested, don't go directly to their homepage mmoah.com to contact customer service.
