The coin is based on a meme, it can't attract intelligent professionals to it.
Don't take this to be anything personal.. But this coming from someone who runs a casino? What "intelligent professional" plays games with his money- Games that are rigged for him to lose a majority of the time? You profit off the unintelligent every day. You see- People don't need to be geniuses to make, and have money. Maybe we have a different understanding of "intelligent" and what role that plays in an economy. (Again, nothing personal, just making an observation, and perhaps a bit of commentary on the ridiculousness of the above quote).
If it attracts the 18-35 crowd- The "intelligent professionals" will quickly take notice. Hell, if it attracts people at first, and converts them all to BTC, and Doge dies.. just as well, right? Unless they are stupid (as in, pay literally zero attention to the risks, and bet more than they can), they've lost very little, and have a better understanding of what they are doing before making large BTC transactions
I just don't get why there's an argument happening at all. Doge has brought thousands of people to crypto, and will continue to. BTC owners should absolutely be thrilled about Dogecoin. Obviously, Doge could never be considered a "threat" to Bitcoin. They aren't after the same market. If you "invest" in Dogecoin- You're probably pretty stupid. It's not designed to inflate. It's designed to be spent- investing a significant amount of money hoping for inflation is silly. Doge will be lucky to ever hit a penny. Bitcoiners should praise Doge as an awesome, inexpensive way to get your feet wet in the digital currency world, and hope that those Dogecoiners eventually "graduate", if you will, and buy some Bitcoin.
If you are too "professional", or too "mature" to have a little fun on the internet (or in life, for that matter), while still pursuing your end goal.. Well, I feel bad for you.
edit: Things like Dark Wallet may bring those "intelligent professionals" to Bitcoin, et al. Darkmarkets, Drugs, weapons, murder for hire- Now that's an image booster! The exact things that have sown such public mistrust, and skepticism to Bitcoin are now being promoted, and touted as victories. We're begging governments to view Bitcoin, and all digital currency as nothing more than drugs and money laundering.
