The move from these teo trusted sites is to protect those that are new to cryptoworld that are vulnerable to online scams using crypto to get money from innocent people. This is actually good for everyone. Not all people see the goodness in this act by facebook and google. If this gets implemented, people will only buy bitcoin in legit sellers and websites which means many people will now trust that they will not be scammed. The only reason why some people didnt invest earlier was because of fear of being scammed. If google and facebook will remove this vulnerablility then this will enhance the value of cryptocurrency and might bring the price back up.
Being a ban in facebook and google about cryptocurrency,for me is have a big positive impact in the world of cryptocurrency because for me in this implementation would affect those fake ICO or phishing site to not penetrate or done there own evil ways to deceptive or scamming the asset of those who make a right bussiness in this community or the legit ICO,and also to protect the image of this bitcoin community forum,to still clean from all negative thoughts and spamming.
This was what I was pointing out not that far of a time ago. Image of Bitcoin gets ruined because of all these shitty ICOs that doesn't even reach anything in their innovations or creation of new coins that could have provided convenience to a lot of people but instead it was all just for go-go money or simply ponzi. I am not gonna invest in any advertisements of coins in Facebook, I tell you. Facebook is really a large social networking site. It is a large space for advertising but that large space could be also flooded by large scams. A closed community like this forum is already enough to advertise different coins. How about the external factors like the people who doesn't know every single definition about cryptocurrency? Referrals, introduction or conduction of study could work. People are curious of the new but it doesn't mean that they will already be interested, but with this system and network that Bitcoin have, I think that people will be really curious of it.
