Dogecoin is great for bitcoin.
People firstly need to realize Dogecoin is not any better in any technical way then any other coin. You may call that a shitcoin, and there are some shitcoins out there designed only to make a few rich. Dogecoin is not one of those and I will explain why...
First of all, realize that the best technology does not always win, in fact most of the time its the best marketed technology (ie VHS/Beta or Bluray/HDDVD). Also sometimes the first(and second) version of a technology is ahead of its time (ie Apple Newton/Palm Pilot, Sega Dreamcast (Online) or Web TV). Also some technologies stick around just because its good enough (fax machines. SMS text messaging, windows xp)
Though many of us believe that Bitcoin can become something your average joe can use in his everyday life, could replace paypal, even take a sizable chunk of transactions away from credit cards. But there are people who think bitcoin has nowhere to go but down from here. They are intimidated by it. It has a fairly large price. The media has mocked it and MOST people believe it fluctuates 50% or more every day. The second problem is Bitcoin is a hard sell. I've been into Bitcoin for over two years and I can't even sell it. I don't know how without telling people stuff they don't want to know, don't want to hear or simply don't understand. I can tell them about cryptology, I can tell them about the federal reserve and inflation but most people are not intelligent enough to understand. They think the fact that the middle class is getting smaller, the fact that many people with degrees and grown adults work $10-15 dollar an hour jobs is because of who we have as president or who we have in congress fucking things up, or just because the economy is bad. The United States has went from inflating real estate to inflating the stock market, so why create jobs when you can make money the easy way? While other countries are still inflating their real estate or just printing themselves out of bankruptcy
I like to think of Dogecoins as internet points you send to someone that happen to be worth something. Your grandma may use them to buy some hearts for candy crush some day. The fact that regular people can still mine it helps as well. Let's face it most of us got here by first mining not buying coins. Bitcoin also eventually won't have room in the blockchain for grandma's candy crush purchase. So we need another chain for smaller transactions, why not Dogecoin?
