You're disillusion if you think DOGE will reach $1 within 3 years. The giant supply should be enough to tell you that. From today's price it would be roughly a 200x to reach $1.
Once BTC goes to 500k or even 1000k it wouldn't be that far fetched to see Doge at $1. And BTC at >500k within 3 years doesn't seem impossible either. I wouldn't hold my breath though.
