He could still have plenty of BTC in his savings.
Those that believe in Bitcoin will keep some as investments. If however you are planning to buy something that is available on a site that accepts BTC then it makes sense to support that website by getting just enough Bitcoins from an exchange to immediately purchase the item and support the Bitcoin economy. By doing this all our BTC will go up in value.
I agree
A successful pizza place that accepts btc would be a nice investment than juz keeping the coins to myself. it'll be boring to juz wait around waiting for the PERFECT time. to me it's like waiting for the day i'd die and i'd spend everything on the last day.., pass the money around in support to the community...
it's his money, his bitcoins, his pizza to enjoy... he felt it's the right time to buy a pizza that day and made him happy...
happiness = priceless
