Delta exchange is a Derivatives exchange platforms that offers perpetual and futures trading. It supports Bitcoins and over 30 altcoins. Registration on this exchange is very easy and fast, after providing my name, email and password i was sent a code which i used to verify and activate my account. Trading comes with nice bonus in this exchange, you can get a maximum of $100 by just making a deposit of $1000 but i made a deposit of $100 i got a bonus of 10% which gave me a $10 bonus. Trading with perpetual wasnt actually my thing until recently so i went for leverages with less risk because i first tried out 100× which accounted a major loss so i settled for a lower leverage rate of 20% and gradually i am moving to higher leverages. The interface of this exchange is professionally designed to give it the best taste and choice for traders. As for the trading fees the exchange does a nice job charging only 0.1% for makers amd takers, pretty cheap. The language barrier is broken in this exchange as Delta exchange comes in English, Chinese, Korean, Japanese, Netherlands, Turkish and a range of other languages. There are several investors in this exchange thay make it a successful derivatives exchange, they are Aave and CoinFund. I am currently reviewing the mobile app of the exchange though it is not the official exchange, i am still skeptical about it.
