I have noticed when trying to trade bitcoin on Coinbase that the current price is different then the trading price. If you sell its always at least $10 less and if you buy its $10 plus more. So for example if its current posted price is $2500 if you sell it will show you selling at $2487 etc. I don't know if all the exchanges are like this since I'm new to this. But if this is the way it is then that would mean the current price is meaningless because when you try to sell your coins it sells for less and if you want to buy coins, your purchase price is more. So what is the point of posting an unusable value?? This seems to me like double dipping since they also charge you a transaction fee. Unless I"m missing something. Can anyone explain this? Thank you.
That's business and all exchanges are like that. That's why you can see that there are different buy and sell rate at all exchanges around. Also in Coinbase, you are dealing trades to them and not on the usual trading with other traders around.
That's why do buy or sell at exchanges that you feel comfortable with the rates. If you want a real time trading with somehow close to the current price, do trading at the actual trading platforms.
