As, we know that Btc & ETH are the top two Crypto in the market but I am confused why Elon interested in Dogecoin?
I saw Dogecoin having a huge price hike when Elon tweeted, The real fight is between fiat & crypto. After considering it, I support the latter. Musk has previously compared bitcoin to other coins and has frequently tweeted about cryptocurrencies, causing bitcoin and dogecoin to fluctuate in value. This is what causes Dogecoin to go higher, it's just that we are waiting on which Altcoin Elon will provide support. I don't know for sure the real reason why support Dogecoin.
the only thing was Elon must tweeting negatively about Bitcoin, that was what was also contributing to the price dump of Bitcoin at the time but not that he promoted Dogecoin over Bitcoin. Bitcoin is a force on its own tweets from Elon must and people like him can only shift the market a bit but not affect Bitcoin negatively in the long term.
