Some time ago I read an article on DetikiNet.com, that google will raided all ads smelling digital currency or like Bitcoin. as spoken directly by the Director of Sustainable Google ads (Scott Spencer)
For various reasons from harming consumers and so forth.
But now you can still enjoy these ads until the end of May. Due to the removal of ads with cryptocurrency or other digital currencies from June 2018.
Even in Indonesia itself there is also a ban on all digital currency transactions such as Bitcoin, many banners displayed in the area Menteng - Central Jakarta, but I have not been able to take pictures at this time.
Hopefully this article can make an observer of all steemian's friends.
