No, you would have $1500 in bitcoins. This feels completely different to having the same in $, because you've already made the leap.

Only if you had invested and cashed out would you have $1500. And then you might feel exactly the same as you do now in a weeks time. Then again bitcoin might crash and you would feel good for getting out now.

If you want to invest you have to be entirely willing to lose all of that money. You can't lose money that you didn't invest so it is pointless thinking about the past.
