What's the best way to market a crypto app?

So I'm given the task of marketing a crypto app by my boss. The app just gives you analysis and market news with no auto trading. Our target user is people new to crypto.

Right now I'm just trying to get signups. Where do you think is the place where I can get my first users? X, Tiktok, Telegram, or SEO?

Please I'm a new grad with very little marketing experience and I am also new to crypto. The job market is tough so I don't want to lose my job 🥹

Thanks everyone!
