I don't remember the details but as I understood the merchant took Dash for payment and that payment was instantly converted to BHAT at a very low fee. This was suppose to be much lower fees than visa.
If you can get a crypto.com card this could be a solution to eliminate the fees you are paying. I have not sold any Hive but I checked an you can trade it on simpleswap.io. If you trade it for a low transition fee coin such as VET, ALGO ect then use this coin to top-up the card.
I use this method almost exclusively traveling in SE Asia. There are also no foreign transaction fees and depending on the card you get there are no ATM fee up to certain amounts. And for me the Thai ATM fee's of foreign cards sucks.
Also I sent a generic link before. Here are a few better ones. If you are in Bangkok Felix and Sascha are great guys and have been boots on the ground in Thailand for over three years onboarding merchants. I went to several of their meet up's and at one time was a big fan of Dash.
Cheers & good luck!
