for now, i think there are no person will do this and spend their 10,000 altcoin to buy something, better to hold it in a moment. but if the altcoin is really worth and the price can up high, then i think people will use their few amount to buy like pizza or another product. but its only still a dream before its come true and we need to wait until there is a store that will accept payment from altcoin.
It depends upon on what alt coin are you holding. If you are holding some potential coin, i think it is not advisable to spent but if it is just a shit coin and got it from bounty campaign then don't bother to bought it a box of pizza.
