Buying Bitcoin can be done in various ways. You can exchange it on a peer-to-peer basis in person with a friend, which is as easy as it gets, but when it involves strangers not always safe. Some platforms allow you to buy Bitcoin using your credit card or you can find a local Bitcoin ATM, but both these methods charge high fees - usually above 7%.
AAX offers an OTC marketplace where you can buy Bitcoin with fiat currencies such as US dollar, Hong Kong dollar and Chinese Yuan. It is essentially a peer-to-peer transaction where you can come to an agreement with a certified merchant on our platform, but AAX provides oversight to ensure every party sticks to the agreement.
Once you have Bitcoin in your account, you can use it to buy into other cryptocurrencies, or convert your balance to a more stable coin such as USDT and use that to trade with.
