Actually he probably still should have (and perhaps would have) taken this public, as they have failed to deliver the instrument in a timely manner and the OP could have bought and sold bitcoin taking advantage of price movements.

This is a clear case of "bucketing"[0] whether done intentionally or not. Its illegal regardless if it seemingly "worked out".

If the price went back up to $1500 a coin, Coinbase would cancel his transaction whether he wanted them to or not despite the supposed price lockin (and return his dollars in their own sweet time). Their usual justification is "excessive risk".

They also have an history of halting Bitcoin sales when it's value drops too much.

Course not.

But all I am asking for them is that they had delivered the coins on the day they said they would.

If BTC went up, I would have had no advantage of them crediting me the coins on the day it was actually due or today.

Understandable, thanks for your response.
