I'm A FOREX Trader Trying Coinbase. A Trading Question

[David92506]

COINBASE                                                     FOREX
I Buy Bitcoin at Market, $20 USD                     I Buy a pair at Market, $20 USD
The order is immediately filled                         The order immediately goes through
The order is now closed.                                  The order is still ongoing
I either won or lost $20                                    I can get out of the order when I want to. If the price keeps going up I can get out at the higher price.

Can I place a trade with Bitcoin with the same dynamics as Forex?
For example, I Buy Bitcoin at Market and I wait until the price goes the highest I think it will. I then get out.
