Thanks for all the help guys!

I made my BTC back in 2012 and I feel it would be the best time to spend it and upgrade my day to day life.
I was looking for the most valuable option to use it and honestly a way to pay less Tax on it. I found a website called Zeek.me that sells discounted gift cards for all the top UK brands and they take BTC is a currency, anyone knows anything about that?
I also registered to local BTC exchanges and a buyer wants to meet face to face for a cash exchange, do you think it's safe? I don't wanna be carrying around 15k...

Hello,

I’ve made some nice amount of BTC and am looking for a quick and secure way to trade and use it, mostly in the UK.

Any ideas?
