This might be partially true. I think not all crypto ads are being banned. Only some that are somewhat misleading. Yet the advertisement industry of cryptocurrencies in many social media platforms are still continued. If we all just ensure the quality of our contents in ads, no social media will ban it. I advice to everyone on that field to be more creative and keep up the good work. Advertisements are very essential in our market because it increases our popularity and advocates people to join our community.
