A tip for buying from coinbase uk

After doing some calculations i was a bit shocked at the money ive wasted on coinbase.

If you buy bitcoin from coinbase from the U.K. you are paying almost of £90 over the poloniex price.

If you buy ether you are paying around £12 over.

If you buy litecoin its £1

This is also before you pay any fees.

Ive not really noticed before so im not sure if this is normal but i will be keeping an eye on it. As the options are limited in the uk they have a monopoly.
