Although this is a good news but not a positive signal for the market as there are many other influencing factors such as whales, futures contracts, the effect of margin trading. We need more good news, but from this news, Facebook has not been able to keep up with the increasingly popular crypto market. I believe the market will recover soon, there are rumors Facebook wants to buy Coinbase, which is also a rumor bearing positive.
It is good to see Facebook softening its stance against the cryptocurrency market in general, but I doubt this will have a huge effect on the market since the market will most likely continue to stay bearish and would only reverse if a plethora of good news comes forward. This is highly unlikely if you ask me. This year has been particularly unfavorable for cryptocurrencies so far, but I am hoping that the 2nd half of this year will be a different case. Also, many investors would think twice before trusting a company like Facebook that sells its data to companies.
