Facebook absolutely works for crypto, but only if you use it as a cheap top-of-funnel filter. Trying to convert users directly on FB or holding discussions there is a quick way to get your assets or pages nuked by their automated compliance AI. The best setup right now is using FB to capture the initial attention with broad, educational, or meme-style angles, and then immediately driving that traffic into a private Telegram group or an X community. That way, you take advantage of Meta's massive audience and low-cost clicks, while doing the actual converting and retaining where you can’t get banned.
