That's stupid. Bitcoin's Liquidity is steady compared to the unpredictable state of Dogecoin. This kind of events doesn't really marks any era. This just shows how influential Elon Musk really is to be able to make people (even those who are not investors) invest in Dogecoin.
I haven't studied the tweets made by Elon Musk in detail. But from what I have heard, he never recommended anyone to purchase Dogecoin. And most importantly, Tesla has purchased Bitcoin instead of Dogecoin or any other altcoin. And that makes it very clear which cryptocurrency Elon prefers for investment. A few people misinterpreted his tweets on Dogecoin, in order to create a pump-and-dump cycle with Dogecoin. Those who got fooled and made their investment are going to regret about their decision very soon.
