Japan Taotao Cryptocurrency Exchange Set to Launch

Taotao, a Japan-based cryptocurrency exchange backed by Yahoo Japan subsidiary YJFX, revealed on Twitter that it will launch on May 30. Initially, Taotao will offer spot and margin trading in bitcoin (BTC) and ether (ETH). Customers will also be able to margin trade in litecoin (LTC), XRP (XRP), and bitcoin cash (BCH).

Originally, Taotao – formerly known as BitARG Exchange Tokyo – planned to go live in the middle of May. On May 16, however, they announced their decision to postpone the launch until the end of the month.

In March 2018, Yahoo Japan-owned YJFX, a foreign exchange transaction service operator, purchased a 40 percent equity stake in BitARG – as it was then called – for almost $20 million (USD).

Without this information, reconciling individual holdings with the currencies held by Cryptopia will be impossible.”
