As, we know that Btc & ETH are the top two Crypto in the market but I am confused why Elon interested in Dogecoin?
It's caused by he was an agenda for doge coin. Remember that elon was mentioning on his tweet if he needs a crypto that can be used in mars and doge coin is including on his project.
he was also buying lots of doge coins and you must see that there are some addresses that owned more than 50% of total supply.
Elon will not buy something if that will not be really useful for him. The communities have been talking about this since at the end of last year.
Well Elon called for developers to try and upgrade Dogecoin. I think he is serious in making the memecoin a top tier coin and possibly adopting the coin and make it his own. I think he has profited much from the sale of DOGE, not sure how much but we know very well he profited. DOGE is a bit expensive now for being a meme token, and anyone who invests now might need to wait from time to tine, to see if the coin has increased price.
