Pionex launched in 2019 out of Singapore with one idea: put the trading bots that hedge funds pay for inside a retail exchange and give them away. Today it ships sixteen of them, grid, DCA, arbitrage, rebalancing and more, sitting in the same panel as the buy and sell buttons. It lists more than 400 coins on the global platform and charges a flat 0.05% on both sides of a spot trade, with nothing extra for running a bot. That combination is why it has a loyal following among people who want to automate a strategy without learning an API.
The American version is a different product. Pionex.US is a separate entity that registered with FinCEN as a money services business in April 2020 and has been collecting state money transmitter licenses since. It carries a shorter coin list, funds by ACH, and reportedly does not serve New York, Alaska, Hawaii or the U.S. territories. If you are reading this from Georgia or Florida, Pionex.US is the platform you would actually sign up for, and it is the one this page compares.
Anytime Capital was built for a different job. It is a U.S. company that sells to customers worldwide, with a storefront at 2549 Piedmont Road NE in Atlanta, an office in Miami, a phone number that reaches a person, and nine ways to pay, including cash and same-day wire. It does not run bots. It sells you the coin, delivers it to a wallet you control, and gives you a bank account and debit card to cash out into. The two platforms overlap on "buy Bitcoin" and almost nowhere else.
