3. Cloud Crypto - Services provide complimentary Bitcoin when you use their cloud mining capabilities.
4. Spreading the Word - New crypto projects give Bitcoin bonuses for referrals, increasing their community reach.
5. Microtasks - Faucets distribute satoshis for completing simple actions like ads and captchas.
6. Freelancing - Projects pay freelancers in BTC for marketing, programming, testing, and other odd jobs.
7. HODLing Together - Crypto Telegram groups share satoshis for participating in discussions and helping newbies.
