Terima kasih!
Is it possible / safe to use coinbase.com, binance and kucoin too?
or should i stick to the local exchanges?
Yes, it still possible, and you can use another exchange too. There's no restriction for it.
Most people in indonesia that use local exchange just for converting their crypto assets to IDR, or IDR to crypto. Because local exchange support local payment and easy to use.
okay thanks, that is good to hear. So maybe i can stick to my common exchanges from my home country
