Doge is very risky investment. I'd suggest to stay away from it as it's just pump and dump. I'd rather hold coin that can have some usability. You can make quick money from doge but i wouldn't suggest to go all in.
That's right, everyone can enter Dogecoin and take profit for a while, because it won't be good to linger on a coin that has a big risk like Dogecoin, because the disposal of Dogecoin is different from the disposal of other tokens.
