John Mcafee is nothing but an idiot who has promised to eat his dick off and don't judge me but I would love to seem him doing that. He is nothing but a crypto enthusiast just like you and us the only difference is that we use our brains a bit and he doesn't. Earlier I used to think of him as an intelligent investor but all he does is buy a coin and then make statements regarding it. Whilst enjoying his normal routine life daily. Coming to doge coin it is one of the oldest altcoins and best altcoin to be used as medium of exchange due to low transaction fees. So it's definitely going to have some value in future.
