Doge is not a coin that is advisable to invest in as it is just a meme coin with no real and concrete projects backing it. Though it does well in price speculations, that's about what its god for. Don't pour your investments there while there are other better projects out there.
Okay, so tell me what exact "coin with project" are you using not only for trades, but also for something else? Eh? Stop telling silly things, no one coin is used for anything except selling and buying
