In my continous empirical study of asking people about their thoughts and impressions of Bitcoin, I can't help but notice that most people have no faith in its success. That is if they at all have ever heard about it. Most of the people I ask -- especially the ones that are not in IT -- still think of it as silly internet money that can't be used to buy anything.
First of all I want to clarify that this text is purely an opinion. That opinion is that Dogecoin will make it simply because it is exactly what people think Bitcoin is. Silly Internet money. Think about it. One day someone makes an altcoin based on a meme as a joke, and suddenly Dogecoin has a market cap of more than 14 million US dollars. That's hilarious. It still can't be used for very much (at least in terms of buying groceries and such), but for now it allows people to play around with crypto currencies without having to invest large amounts of money.
That's where I see the real value of Dogecoin. In being the gateway drug of crypto currencies. For not-so-technical people I think Bitcoin can be confusing at first, and I think it can be frightening that you have to invest so much money (~USD 290 = BTC 1) to get even one bitcoin. With Dogecoin on the other hand where 1 USD currently approximates to 7,000 Doge (March 15, 2015), it's possible to play around with something that feels like a real amount without having to risk your life savings.
Anyways. The reason why I love Bitcoin based currencies is because of the security and simplicity it offers. That said, it does undoubtedly take some time to get used to, and I understand that it may seem complicated at first. Dogecoin is fun and simple, and it let's people get familiar with the technology with close to zero risk. That's where I think its potential lies, and I think that's why it will succeed and grow alongside other blockchains. At least it's how I got introduced to and fell in love with Bitcoin.
