My answer is yes, to some certain extent! Elon inflated the market in 2 specific occasions as we all know! The first incident is when his company bought billions worth of bitcoins and the 2nd  incident is when he pushed for dogecoin. If you see the price of both of these coins, you will understand the difference. The bitcoin market has find a stable support at 52k and the dogecoin has increased by 700% in last few days. So there's no wonder that Elon pushed for these coins and the market reacted as expected pushing the prices to the next level.

Some people like me are still trying to recover thousands of dogecoins that we had back in time.
