With Facebook, Google and Twitter crypto ad's bans where new projects will be promoted? Maybe we will see some new marketing strategies?
I doubt facebook will ever ban crypto since they are looking into it themselves. These new "bans" on bitcoin and other crypto currencies is just a temporary way to find a way to fix some glaring issues on phising and other ad related bad things going on, as soon as they figure out a new way to roll out advertisement with some protection to it just like in other fields the ads will come back.
I know people who spend hundreds of thousands of dollars on bitcoin advertisement on related projects, I am sure google and all others are making tens of millions of dollars from ad revenue thanks to bitcoin and the surge of interest to it, so there is no way they are keeping the ads banned for a long time.
Guess, these bans are connected with the fact that large companies develop internal cryptocurrency solutions themselves, and there's a legal uncertainty, and giants are very sensitive to such dualities and aren't ready to undertake risks which may bring losses!
