So economy impact rising, investing still not advised. That would render a future for tipping stuff, reddit style and such. DOGE has a nieche future where the biggest coin could not prevail (TX Fees!)
This is exactly what Dogecoin is, without ever really having said so. It is a niche coin, with a famed legacy of tipping/charity/generosity in the crypto community. So many other coins try to develop in their own niches (ETH for smart contracts, Monero for anonymity) but very, very few actually get used in their practical, intended sense. Doge has a niche market, and its future lies there.
