Dogecoin, the 140-day-old cryptocurrency, held its first conference in San Francisco on Friday where hundreds of the currency's devotees turned out to show their support and, of course, "tip" anyone with a QR code handy.

Jackson Palmer, co-founder of Dogecoin, a cryptocurrency that uses the Shiba Inu dog character from the "Doge" internet meme as its mascot.

Dogecoin's Sydney-born founder Jackson Palmer gave the keynote during which he discussed the currency's unexpected journey from joke to reality and the future of the cryptocurrency that in just over four months has already become the most widely traded virtual currency in the world.

Palmer, who was involved in other cryptocurrency communities at the time, officially launched dogecoin in December of 2013. The currency was quickly embraced by the Reddit community who has collectively given out $US150,000 in dogecoin "tips" to other Reddit users, Palmer said.
