El Salvador government will on the 7th of September accept bitcoin as a legal currency within the country, can we say we are in for another long runoff for Bitcoin market.
It is only a reason to hype the market. Legal tender in El Salvador won't change the whole picture and global adoption of Bitcoin.
Additionally but more importantly, this positive news already was reflected on the price of Bitcoin.
"Buy the rumor, sell the news". It is not a new news and you can not expect too much from it.

No you're wrong IMO, Bitcoin price market doesn't work like that, sometimes a news is still bought several days or even weeks after it came out. Moreover this news was still hypothetical as long as it was just a law that could have been cancelled and we are yet to see how salvadorian authorities will apply it.
