I don't think that Dogecoin will grow even higher, let alone become a new BTC, because I think it's very difficult for Memecoin to compete with coins that have very high capitalization and popularity like BTC, and I don't think Dogecoin is worth comparing with BTC because the difference is very far, namely like copper and gold.
That's right, a coin that many won't beat the power of BTC because BTC was the first coin to exist, memes won't beat reals coins.
