With Elon onboard, we can definitely expect some cryptocurrency integration into Twitter's native platform. But it might not be Bitcoin. While Elon is very much bullish on Bitcoin, he sees it as an investment rather than a currency system. The chances are higher for cryptos like Dogecoin or ETH which are faster and cheaper as a currency.
But it's too early to judge whether it will be good for the market or not. Also it's too early to say if cryptos are going to be integrated or not.
But whatever crypto he's thinking to integrate on this platform, for sure it will give positive impact towards the crypto market.
By the way, ETH is not cheap when it comes to tx fees. But I can agree with doge, it has high likelihood of getting deployed in this social media.
So now, people are anticipating on the next progress for this news. Some people may be on the buying spree already for doge.
We can't deny the fact that Elon has influence on this market. So we can't say, he's not doing anything when it comes to popularity of crypto.
