Pionex splits the world in two. Pionex.com serves most countries and does not accept U.S. residents. Pionex.US is the American platform: a separate entity, registered with FinCEN since April 2020, holding state money transmitter licenses and adding more over time. It runs the same bots on a smaller coin list, funds by ACH, and reportedly does not serve customers in New York, Alaska, Hawaii, Guam, Puerto Rico or American Samoa. If you sign up from a covered state you get a licensed, if narrower, version of the product.
What Pionex.US does not have in the United States is a customer-facing office, a phone line, a cash rail, or a domestic wire desk. Its licensing is real, but the company you are dealing with is still on the other side of a chat window. Anytime Capital is a U.S. money services business with a storefront on Piedmont Road in Atlanta, an office in Miami's One Biscayne Tower, and a phone number, (470) 748-2530, that reaches a person during business hours.
The practical split is simple. If you want bots and can live inside ACH limits and the state list, Pionex.US is an option. If you want to buy Bitcoin, Ethereum or USDC with cash, a wire, a card or Cash App and hold it in a wallet you control, Anytime Capital does that today, and its free non-custodial wallet is where the coins can live afterward.
