5 days ago I bought 2 btc @ 320 each. Today the btc suppose to be clear in my coinbase account @ 615 each, When suddenly i receive a coinbase email stating that the transaction is suspicious and my money has been reversed.

I had almost $100k back and forward with coinbase for the past year and never had any problems at all but today they shut my transactions because of this bitcoin raise.
Not a good strategy for coinbase.
