I've got some Thai friends who are holding large amounts of cryptos like BTC, ETH and OMG, and they advised me NOT to withdraw from BX in THB as I might have to pay taxes (different from capital gain on securities which is tax-free, since it seems that cryptos are considered assets).
Anyone if you guys have actually withdrawn "large" sums from BX (> THB 1,000,000) to your local bank account in Thailand?

(Someone even advised me to use Kraken instead and withdraw fiat to a bank account in my home country, since I'm not a tax resident there anymore)

Sadly tax and meeting your maker are facts of life - you imagine the members of Thai Visa are financial whizz kids? 

If so they would be in Monaco.

Or you can buy the btc and try to sell locally for cash on localbitcoins

It will take you a long time to open and account and get verified w kraken.

I think kraken only lets you withdraw fiat to US accounts.

There is a bitcoin meet up group in Bkk every Monday. U might get some good ideas on how to move the fiat out without getting taxed. I buy btc and pay cash on the spot. Send me a private message if u want to sell

Great stuff. Thanks guys
