A write-up of my favourite methods for passive income / free crypto!

1. Staking: You "freeze" you coins and recieve an interest in return (usually ~5%). This can be very benefitial if you plan to HODL anyways, but tax reports for it can be a nightmare in some countries.
2. Mining: Making your PC do computational work in order to support the network. If you have a gaming PC, you can most likely mine ETH with a nice profit (up to ~150$ per month atm). You can quickly get an estimation of your profits if you select yur GPU on whattomine!
3. DeFi loans: You lend money to others on a DeFi platform and earn up to 10% interest on it. Can also be done with stablecoins which don't have the volatility of traditional crypto.
4. Yield farming: Another way of lending your crypto, this time to a trading protocol and recieve some of the trading fees in return.
5. Air-drops: Air-drops are sending small amounts of a new coin to a lot of different wallets in order to promote it. You can sign up and get tiny amounts of free crpyto, but I'd recommend using a new, empty wallet for it as airdrops have also been used to attack ppls wallets.
6. Games: Yes, you can get paid to play video games. Some offer you NFTs or small amounts of crypto as rewards. However, the amount is usually pretty low unless you play for a long time. Also be aware, there are a lot of scams out there (e.g. some games seem to just ban users that started making a decent amount of money). Some suggestions are Wave Ducks, Spells of Genesis, Beyond the Void, Huntercoin.
7. Coinbase/coinmarketcap rewards: You can get rewards for watching videos about crypto/defi/trading. Probably doesn't just apply to only coinbase, but it's the one I am aware of!
8. Moons: Probably the most obvious one. Shitpost to farm them Post entertaining and helpful content and recieve moons as a reward for upvotes!
9. Brave Browser: Blocks tracking and rewards you with crypto for ads that are displayed!
