As, we know that Btc & ETH are the top two Crypto in the market but I am confused why Elon interested in Dogecoin?
Because Dogecoins were still very low priced at that time so he could play his game by pumping Doge prices high after he held a lot of Dogecoins at low prices. Actually he is a person who likes Bitcoin and a person who is trying to make Bitcoin a transaction tool in his company.
