You're pretty much looking for free money. I'm sorry but you need to realize how silly that sounds. Unless you want to slave around using faucets
(which is definitely not recommended).
Look for a way to earn money, whether it'd be by having a job, a gig, or a business, etc. Then use your earnings to buy bitcoin. That's pretty much it.
Another method could be to do some of the airdrops. However, these can require KYC and several social media tasks to qualify. Some of the tokens will also most likely be worthless too. There is a chance though, that one of the tokens you get airdropped could take off in the future and be worth a chunk of change in the future.
Airdrops aren't "free". You pay them with your personal information, which is much much more valuable in my opinion.
