Coin Hunt World: A Crypto Adventure
Overview: Coin Hunt World is a location-based game available on Android and iOS. It offers a fun way to earn small amounts of Bitcoin and Ethereum while exploring your surroundings.
All these methods you had discussed here, one can get a small profit but I don't think he can earn a lot from these method. Also, these methods are for a person who is new to crypto, or who is a beginner. Although it can help him a lot for seeking knowledge about the crypto industry, and also he can have his food expenses, his internet package and his other little daily life expense. But I don't think in the long run these methods will help an individual to make a big profit from these.
These are the methods you can use to earn free cryptocurrency
Eg :
1. AMA(Ask me anything)
2. Testnet
3. Play to earn games
4. Bounty
5. Ambassador Programs
Bounty is not a good option I think now a days, as we have seen no projects is going to pay the amount they offers, and mostly the project didn't list. As in 2021, 2022 there were some great project who pays users a decent and great amount but now can't think that project will pay huge.
Also, Play to earn games required a lot of time, after that they can give you less money.
