30+ Bitcoins? who's him? I think you're refer to Laszlo Hanyecz where he spend 10,000 Bitcoins for 2 pizza and he was not disappointed for doing it, so why you should care with it?

It's your choice if you want to pay with BTC or not, but I believe there's a time where you will convert your Bitcoin to cash because you will need that money in the future, you can't just hold it and not enjoy what you've accumulated so long.
