So at the moment it is not possible to withdraw JSE to your local currency. We plan to ICO in 2018 and then list on exchanges. At this time you will be able to trade JSE for BTC/ETH on a 3rd party exchange and then transfer to your preferred fiat currency.
Are you looking to exchange JSE to your local currency? If so please see the message above. JSE will be launched on exchange as an ERC20 token which will then be compatible with exchanges, 3rd party wallets etc. The process to convert to fiat currencies will be JSE > BTC > LocalBitcoins(or other merchant) > Fiat (USD/EUR etc.)
