We shouldn't too worry about this. First, why don't Google ban crypto ads now instead of waiting to June? I think we need to consider this news. But if Google is really ban crypto then it's not also much affect to the price of Bitcoin even cryptocurrencies. Maybe scam ICOs will be affect the most because they are people need to run ads the most. All of coins which listed to exchange sites is dont need to run ads. So Google ban crypto ads is no problem with cryptocurrencies.
