DOGE reaching $1 is not impossible as you say but if it does get to that it will not reflect the true value of it. The pump is the only cause people rush to buy DOGE not its value as an asset. If this was to happen then it will only be a matter of time before the bubble bursts.
A meme coin with no real usage managing to get a market capitalization of $50 billion. The only question now is when the bubble is going to burst. It can happen tomorrow, it can happen after one month, or it may not happen this year. Among my friends, I haven't tried to discourage anyone from investing in Dogecoin, because if it can move from $0.5 billion to $50 billion in market cap, then it is definitely possible that it may go up to $100 billion in the future.
