In this article I will collect various ways how one can earn free crypto with or without investing money I will also mark each category based on this. Hope you are gonna like it!

Learn & Earn - Require's no investment:

• Coinbase: This is by far the most easiest and convinient way to earn free crypto without investing all you need to do is signup for coinbase complete KYC and than you can start completing short quizzes to earn crypto. I have earned so far about 60-70$ by doing this. I got around 30$ worth of quizzes at the start and overtime I got another 30-40$ since I started using coinbase. What's more you can also earn another 10$ in BTC on coinbase when signing up with a referral code and buy or sell 100$ worth of crypto!
• Binance: Binance also has a similar program as coinbase wich i just found out about a week ago, but it's much harder to get rewards there since there is a much more limited time period to complete the quizzes so keep an eye out for their announcements otherwise your gonna miss them.
  The last time on august 4th you could earn about 9$ in various cryptos by completing the quizzes.
• Cake Defi: Cake Defi also has a learn and earn program where you can earn 10$ in crypto by completing them. They also have a referral program but since their ecosystem is not at it's greatest I wouldn't personally lock up my assets in there just to earn theri 30$ in DFI tokens but if you are interested you could take a look at that as well.

Exchange referral programs - Require's minimal investment:

• Coinbase: As I mentioned before you can earn 10$ in BTC on Coinbase when you complete KYC and buy or sell 100$ and use a referral code.
• OKX: Currently you can earn Mystery Boxes worth up to 10,000$ in crypto when signing up with a referral code and downloading their app. You can also earn another Mystery Box when you complete KYC and deposit 50$(Usually this one has more rewards in it).
• Bitpanda: Bitpanda requires by far the smallest deposit when it comes to refer and earn programs you only need to deposit and trade 25€ and you can get 10€ when signing up with a referral code and completing KYC.
• There are also a lot of other exchange refer and earn programs that I didn't mention but I didn't try those out yet so I don't know how reliable those are but be sure to be on the look out for these programs!

Surf the web - Require's no investment:

• Brave browser: You can earn BAT by enabling ads but here you actually get payed for watching them unlike regular ads. Also these ads that brave gives are really harmless and sometimes you won't even notice them. And what's better to block regular ads(and youtube ads wich is the most horrible thing ever) the browser has a built in ad blocker which works like a magic and block literally every regular ad. If you download it for phone you can also use youtube while having a lockscreen if you enable play in background in the settings. Be sure to try it out if you haven't yet you won't be able to go back to any other browser after trying it out. Also soon they will launch brave search with brave rewards where you will be able to earn even more BAT! So far I have earned about 30$ since using it.
• Presearch: A search engine and browser extension where for each search you can earn up to about 3 $PRE per day you can also get another 25 $PRE for using a referral code and beeing active for 30days.
• Reddit: Community tokens are also avaliable not only available on the cryptocurrency subreddit but also in the ethtrader and fortniteBR subreddits you can earn DONUTS and BRICKS there. Also in the future I can't wait to collect community tokens on other subreddits. E.g. something on the Hearthstone subreddit. Dust incoming?

Games - Require's no investment:

• Gods Unchained: My favourite play to earn game where I have earned so far about 250-300$ since I started playing. It is a card game very similar to Hearthstone. You can earn $GODS tokens by playing or collect NFT cards which you can sell to earn more. Currently they also have a refer and earn program where you can earn 10 $GODS for free by signing up with a referral code and reaching rank 3.
• Crypto Royale: It is a combined rock,paper,scissors with agar.io. You earn ROY by winning games or taking part in tournaments(which happen daily). I have earned so far about 60$ playing this game.
• Guild of Guardians: A mobile game similar to diablo where you can earn $GoG for playing. I tried it out in the beta but since my mobile was not strong enough for it I couldn't play it so well without lags. But if you have a good mobile with the requirements to play the game be sure to check it out.
• Coin Hunt World: A mobile game where you can earn BTC and ETH by going to various places similar to pokemongo but sadly it is only available in a few regions if you live in the US, Canda, UK or Netherlands be sure to check it out.
• And many other blockchain games: There are a few upcoming ones that I'm personally excited about for example Illuvium and Cornucopias. Illuvium will have an open world RPG as well as an auto chess game within it. Cornucopias is gonna be a metaverse triple AAA game built with UE5 I also have high hopes for it and the $COPI token is one of my 100x investments. There is also the Sandbox, Decentraland, Gala games or Axie Infinity which I haven't tried but they are also really good play to earn games.

IMX tokens for trading volume on ImmutableX - Require's Investment:
Currently you can earn IMX tokens for your trading volume on ImmutableX an NFT marketplace which is a pretty neat option if you want to trade NFTs.
This is also the marketplace for Gods Unchained and Guild of Guardians.

Crypto visa cards - Minimal investment ~ Requires larger investment:
There are many alternatives out there but I will only mention the ones that offer the greatest cashback on your purchases.

• Coinbase card:
  You can pay with USDC and earn 4% cashback in XML or 1% in BTC. No staking is required for the card. Sadly this is only available in the US.

• Crypto.com card:
  Depending on how much CRO you stake your cashbacks may vary here. But even if you don't stake CRO you can get 1% cashback in CRO wich is pretty neat in my opinion. If you stake CRO your rewards can get up to 8% and you can get free spotify, netflix etc. Also cdc has a partnership with booking.com and you can save up to 25% on your bookings.

• Binance card:
  This is also a great alternative but I don't see why anyone would use this instead of crypto.com card it just offers much greater benefits.

Lolli - Require's no investment:
You can earn a fixed %(depends on the brand) back on your purchases in BTC. E.g. you can earn 6% back on booking with lolli. All you need to do is add the Lolli extension to you browser. The only downside is that it is only avaliable in the US.

Faucets - Require's no investment:
There are plenty of faucets out there where you can earn crypto dust. I will list my favourites here: Nano faucets, Doge faucet, Cointiply, Solana faucet and of course Moons faucet. There is also a timer currently in works for the moons faucet which is really cool. Remember to claim these especially the moons faucet since we are getting a lot of moons mainnet hopium.

Airdrops - Require's no investment:
You can sign up for various airdrops on Coinmarketcap or Airdrops.io. Also currently there are many opportunities in the cardano and iota ecosystem to get various airdrops so be sure to keep a close eye on them. I personally expect a few airdrops from anetaBTC and tosidrop to happen in the future.

There is still a last way to earn free crypto which I didn't mention which is tipping a post here on publish0x this way both an article writer and the tipper can get a small amount of crypto, but these do add up quite fast anyway I hope you liked this article and happy earning!
