IMO, I consider for now that it's good news and surely this might be the cause again that Bitcoin will surge price in the market and create another ATH which is my presumption is $50k within this month and most like rumored by some predictions.
I can't give some assumption in the future what will possibly happen, as long as Elon Musk helps the entire crypto give awareness from other investors and also might in institutional investors. And probably more other private business sectors will follow the same as what Elon Musk did to accept Bitcoin as a way of payment.
He once gave a negative comment on Bitcoin last year on his Twitter post.

This is something that I do remember happening , he haven't been stable with his idea of cryptocurrencies, he did support dogecoin and some other things too but at the end we I see by his recent doings he did all of that to attain some profits from the market which is indeed very low and the funny thing is : He knows very well what he is doing since he did commented after something like "what else did you expect to happen".
Now the thing is , I considered this guy in the positive section when we did think about the people but he have done something that people of the market are not only scared of but also it's bad for real , he Manipulates the market time and again. Now this shows the whales that it's all good to do and they also might get influenced and somehow we are stable and we are moving forward nicely and this might ruin all of the plans.
If he is thinking of accepting them as a form of payment , no doubt he is helping in Adoption but this is not what the community needed right now.

Ironically their buying has placed bitcoin above Tesla itself in terms of market capitalization. . Generally speaking I see this as a good sign showing Bitcoin is on the verge of the mainstream. Musk has proved to be a powerful influencer as to crypto, so his decision to play with BTC will push it high. Is this good for poor people, probably not, because price of $ 50,000 or more would mean that fewer people could buy it.
I did not know this fact lol ! Amazing though.
Shower thought. What if Elon Musk’s participation in Bitcoin isn’t only as an investment? What if he will employ his own company, Solar City, to power ASIC mining farms in the United States? THEN miners will be converting energy from the sun into digital cryptocurrency. 
This is a fair idea and I do think you should put it on Twitter and tag him. I do believe that the only way to solve the mining situation is to be sustainable and use renewable sources of energy this might be something that needs a lot of investment at first but it would not only make it healthier for the world but your cost of electricity would be nil!
Good news if you think about adoption since it's in the top corporations list, bad news if you think about the number of coins only one entity now holds. But overall, this is just massive. Props to Elon Musk for sparking the potentially next insane BTC bull run.
We have to for sure keep a close eye on him !! He is planning something big for sure !
