CoinHako, the Singapore Bitcoin Exchange has launched their MYR (ringgit) trading for Malaysian and Singapore residents. Now with one user account, you can deposit BTC/MYR/SGD and withdraw to Malaysia and Singapore bank accounts; now that’s a pretty nifty feature. They are currently using a Maybank bank account for MYR deposits.
On the other hand, Luno, the largest Bitcoin Exchange in Malaysia currently only allow users to withdraw to their country of origin. Hopefully Luno will change their policies to allow users to withdraw to both Malaysia and Singapore side since there are many Malaysians who are working in Singapore (estimated 350,000 according to some figures on the internet)
