Indodax, the largest exchange in Indonesia, with ceo Oscar Darmawan, yes I know that person, one of the exchanges that I often use, because I have a IDR pair, yes because I am Indonesian so I often use exchanges, over the past few years Indodax has changed for the better , with UI / UX that is beautiful to the eye, and the most like of this exchange is the rupiah voucher feature, which facilitates transactions in the form of rupiah, fellow indodax users of course, accompanied by kyc make this exchange more secure, for Indonesians this is good but for non-Indonesian people, in my opinion is not suitable, because most of the pair of tokens / coins are in IDR (Rupiah) form and maybe some features are not used if those who use this exchange are non-Indonesian.
