Nah, it's still used as tips even today the same as I have seen for the past four years in gambling areas. Casinos are always where you see DOGE tipped and rained. As much as I love it, have yet to see anyone actually ask for payment in DOGE (except in casinos as usual).
$12 per coin in 2022? I wouldn't mind but let's not get carried away:)
Now $12 per coin is an insane prediction. It will never come true because of the inflation existent within the coin itself. With so many coins in circulation right now, I fail to see how DOGE could reach a price above $0.25 in the future. Even $1 per DOGE seems to be like a distant dream. Besides, Dogecoin is mostly used for tips and online gambling. The vast majority of people who invest into DOGE for the long term, don't know what they're doing. They simply made their decision based on hype. Once DOGE goes below $0.01 per coin, they'll be regretting themselves by not selling earlier.
Nonetheless, crypto behaves in many strange and bizarre ways. I'd be very surprised if DOGE hits $1 soon. With how wild and crazy crypto land has been as of late, anything can be expected. Elon Musk, Snoop Dogg, and other DOGE shills could pump its price on the market with their continued propaganda. Yet, the effects won't last for long because of the reasons mentioned earlier. There are far better coins out there on the market which make a better investment for the long term. Instead of investing massively into DOGE, people should invest massively into Bitcoin and Ethereum as these coins have a better future. Just my thoughts
