As, we know that Btc & ETH are the top two Crypto in the market but I am confused why Elon interested in Dogecoin?
Elon Musk interest in Dogecoin is a personal matter for him in my opinion. I think your question is good to find the answer for us to make a strategy in choosing our coin of choice. For me, we can learn from Elon Musk who is more interested in Dogecoin than BTC and ETH.
From what I see, Elon must have considered a very strong holder, price, and market. dogecoin is not a new asset in the crypto market. they are very long, sticking with their loyal community. Dogecoin grew their market that was once seen as worthless, so now Elon knows how much potential he can make for the huge Dogecoin market.
