Dogcoin is a great coin. Now on my opinion it is worth buying it, the price is good. It is possible to make x2 exactly, just need to wait
The problem with that 2-3x projection is that nobody really knows what the bottom is. So I expect doge do to its regular 2-3x pump eventually -- but it could be 8 sats to 20 sats. And that won't be so great for those buying at current prices.
