Oh so DOGE was once supported by Elon Musk too huh? Do you have any evidence of Elon Musk supporting DOGE coin? And for the Bullish Season that you mean when will it happen? Is it still a long time until the D-day occurs?
Do you never know about this? I'm surprised if you don't know it. In 2021, it is very hype, Elon Musk made a big surprise by supporting Dogecoin. At that time, he was very often tweets about Dogecoin. I don't think you need to ask someone about the evidence, you can find out yourself by googling.
But it was a past story. It is quite doubtful that Elon Musk will support Dogecoin as well as in the past. Elon Musk looks very busy now, he is supporting Trump to be the next president in US. He will have a small chance to share his time for tweeting or posting anything about Dogecoin.
Indeed, that's the fact, Doge is the first and main meme coin in the crypto market. Its success in the bullrun last season with a very drastic and significant increase has made many other meme coins emerge over time. And one of the biggest factors of the rising price at that time is because in relation to Elon Musk, and that was one of the factors.
Here are some tweets of him about supporting Doge:

Simple tweets, but very big impacts on Doge.
We can see various news of Doge price increases after these tweets and other tweets, because there are many.
