Dog Coin (DOGE) icon Dogecoin was born out of a tweet, a joke. In 2013, dog dog image was so popular that Palmer, a flat-shooting and marketing expert at Adobe Sydney and a cryptocurrencies researcher, tweeted semi-jokingly, "Invest in Dogecoin, this is the next big opportunity." After the tweet, there was a lot of support, and Palmer was very effective in buying the domain name dogecoin a week later. Meanwhile, in another part of the globe, Markus, a programmer in Brandt, has been trying to create a cryptocurrencies. Markus came across the site and contacted Palmer for help. Before Palmer replied, he set out to transform the source code of Bitcoin, adding elements to Doge Mene. Palmer quickly replied to Markus, and the two clapped together. Eventually, dogecoin was born more than a week after the half-joking tweet. Dogecoin was born and developed so smoothly that it can even be described as hot. For Dogecoin itself, there are two main reasons for the boom: First, Dogecoin brings its own social attributes. On social networking sites such as Reddit, Dogecoin's content was very popular before it was born. When Dogecoin was born, it was greatly assisted by sites like Reddit. Dogecoin has far more attention on social networking sites than Bitcoin, Litecoin and other shanzhai coins. Second, Dogecoin's tip and charitable culture are recognized. Dogecoin advocates a tip culture, which has been used by many people for activities such as rewards in just one week, showing the level of recognition of its tip culture. Dogecoin is also more recognized in terms of philanthropy, and its charitable support is already extensive.
