with rules like this, do you still want to go to bali
Yes, I would. Bali is a beautiful place to be.
Although I wouldn't blame his decision on crypto currencies as he's trying to defend the local fiat(the rupiah) against the widespread use of the dollar.
But if I were him, I'd not just accept it as an asset, but also for it to be used in transactions since it would make transfer of funds easier as they will not be restricted by borders and the fees are minimal. And since Bali is a place heavily dependent on tourism, it would go a long way to help because more tourists would want to not just visit, some would think to start business there.
