Dogecoin has its niche, and could be adopted by millions of users, so it is normal that it is among the largest cryptocurrencies and that's why it's been included in this Robinhood list
One whole heck of a lot of cryptocurrencies are now on Robinhood, including the following. Bitcoin, Ethereum, Ripple, Bitcoin Cash, Litecoin, Qtum, Ethereum Classic, Stellar, NEO, Zcash, Monero, Dash, Bitcoin Gold, Lisk, OmiseGO, and Dogecoin. As they say on Sesame Street: Which one doesnt belong? Its baffling to see Dogecoin amongst these other major coins but who knows?https://www.slashgear.com/stock-app-robinhood-ads-no-fee-bitcoin-trading-25517052/Many underestimate the potential of Dogecoin project. There"s a bright future fore DOGE! Just remember that Vitalik Buterin once tweeted that Doge is his huge crush and he will hodl it for a very long time.
What potential can there be for dogecoin, are you serious? Explain to me then the meaning of this project and what is the use of it for society? What important problem does this project solve? A coin is a joke and no more, why such a large capitalization is a mystery to me. It's not serious to talk about prospects at all!

Ask yourself these simple questions:
1. Does anyone truly need a Starbucks coffee?
2. What is the use of amusement parks for society?
3. What is the meaning of Fidget Spinners and what are their potential?
Get the point?
