If you are interested in arithmetic it is more profitable to buy bitcoin. But there is a significant problem. You for life, you must have the Fiat. You will have to sell some coins to provide for their needs. In this case, the number of your bitcoins will be permanently reduced. Coin mining will always be profitable.
I have this in excess of what i need. Therefore the $1500 is here, and ready, to invest.
My question which investment is better?
