No no no not yet! I agreed to sell my 25B coin for $21,000 cash. Meeting him at 10pm going to buy back on coinbase then we can go CHOO CHOO all the way to the moon!
Careful. Sometimes Coinbase decides it is a risky transaction when the price rises between the time you pay and when they give you your coins. They can reverse the transaction if it goes against them.
You can only do 10 coins a week for certain pricing.
This has happened to me with Coinbase but it was in my favor.
