Hi - Just getting started with bitcoin this week, so very new. Looking for feedback if you think this will work.

I have bank accounts in USA and the UK (I'm dual citizen) and I've noticed a difference between prices for bitcoins in US (for example $806 today on coinbase) versus what I could sell those coins for in the UK (a popular site in UK selling today for £520 which is about $860).

Could I not buy a bitcoin or 2 at US prices (using coinbase for speed and low fees -- 1% + 15 cents) and then immediately turn around and sell them in the UK for a US$50-60 profit. I understand I'd have seller fees (another 1% approx) and a fee to convert the cash back to USD to start the process over again. But it could be OK profit ($40-50 USD) for 10-20 minutes of "work".

What do you think?

My main concerns:

1. My US and UK banks would end up seeing frequent transactions in the $1000-2000 range and might flag it up and question it.
2. Price volatility: value of held bitcoins could decrease between buying and selling.

Thanks for any advice.
