I was going to buy some BTC on Coinbase and checked their BTC price vs what Polo shows:
Coinbase: BTC $2,527
Poloniex : BTC $2,464
Delta: $63 or ~ 2.5%
Does this seem correct?
When I looked at Litecoin it was much closer in dollars at first look:
Delta: $1.48 but percent change is 3.1%
So if you buy on coinbase you buy in at levels below current market on Poloniex. Then have to pay a fee to purchase the coins. Then have to pay to transfer the coins…
Is there a better way or am I missing something?
