I believe these type of "billboard wars" going around is not really that smart, it is not going to affect or change anything, look at subreddit wallstreetbets and how they did bunch of billboards all over the nation for GME stock and look at what the price became, it was 360+ dollars, even 400+ dollars for a short while, and now it is 63 dollars after the "craze" started. As you can see even though everyone keeps saying they are "holding" they are not holding, if they actually held their stocks the price wouldn't have dropped this much.
This is why I do not care about some billboard dogecoin has, it doesn't change anything, price is still too high so that's fine, but the moment it starts to crash and people start to get out, some billboard will not be the reason why it doesn't crash, there won't be new people seeing that billboard and buying millions of dollars worth of dogecoin.
Obviously the majority have dump their GME holdings reason where the price drop so drastically, they will keep fooling some naive investors about them holding while behind the scene they are busy selling their GME stock,
It is hard to say if same thing will happen to dogecoin, but the shilling from the top affluence people is huge and making some people to think they could be missing out on something big in near future, some of my friends already talking so much about dogecoin and the huge opportunity of making big profit, am still not convince about it, am just taking my time, i don't want to get caught in the middle.
