Indodax Exchange is the best indonesian exchange that already launch on 2014 with name Bitcoin Indonesian then on 2018 it changed into indodax.
Until now i already using indodax to exchange my bitcoin into fiat and all the transaction went smoothly with the lowest fee if you want to withdraw your fiat.
the one feature that i like the most from indodax is the voucher feature, because with that we can withdraw fiat with more lowest fee using 3rd party that recommend by indodax
