-conversion from other currency holdings (LTC, BTC), which some people have openly said they did
-recent run up / down of the value caused a lot of people who were previously holding to buy / sell (started around the time of the big news push with the Jamaican bobsled team fundraiser, right now it is dropping)
-general interest, people buying some amount to hold for the first time. i have had friends making their first crypto purchase in doge recently, who don't understand the technology and probably shouldn't (due to the news i think and not wanting to miss out on bitcoin 2.0)
-Chinese investors getting in / out? i think i saw a graph of cny to doge being a major part of the transactions
personally, i haven't looked into it that seriously because i haven't invested seriously. i put time in (especially for the site content), but all my coins are mined from an existing gaming computer. my total doge USD value is ~$50, which is probably lower than what people would expect of the dogecointutorial creator. my doge mining actually started because I wanted to cheaply explore how cryptocurrencies worked. then the tutorial site actually started when i was testing out aws / github pages for landing page hosting. originally i just had some sort of dogecoin index placeholder but found myself jumping around / searching for info as i learned about doge and cryptocurrencies...so i started my own guide. if you do more research, do share it!
