I left Hong Kong to the UK without exchanging a single GBP (UK currency). I totally forgot about this and decided that I would use visa.
Bank ATM card didn't work
One problem is that not all restaurants accept visa here, especially the nice kebab shops that only accept cash. I tried to withdraw cash with my Normal ATM card, only to get rejected. This is because i forgot to set the overseas ATM limit before I left, so I couldn't withdraw any cash.
bitocin ATM
I also tried visiting both bitcoin ATMs here, but there were out of cash. https://steemit.com/bitcoin/@boxmining/checking-out-the-bitcoin-atms-in-brighton-uk . Also the exchange rates were quite poor around 2300 GBP to BTC
#tenx to the rescue
I remembered that i Brought my tenx card and I tried it on the ATM. to my surprise it actually worked and I was able to draw 40 GBP! There is meant to be 2.5 dollars of fees, but seemed like they didn't charge me. the exchange rate was great too!
This shop didn't accept Visa - so i got some cash with TenX
Woot got my food!
