Free ways to earn crypto

I have seen a lot of comments lately were people are loving the low prices and wishing they could keep accumulating, but they don't have extra fiat to purchase crypto. Here are a few ways you can add to your stack and accumulate without actually spending money. I am not going to mention staking as that there are risks involved and I don't want to get into technical details. I'm also not going to discuss moons, because as community points, that are not intended to be traded. People who do sell their moons see a reduction in earned moons in future rounds.

• Browse the web with Brave - This is a must. Brave is a browser run on Chromium that offers Basic Attention Tokens (BAT) for just browsing the web. It is one of the best browsers for security and preventing advertising tracking. You can also support creators through the platform with BAT. I've been earning 4-10 BAT ($2-4 USD) / month using Brave. You can link your browser wallet with Gemini and use Gemini's earn feature for more return. This isn't a ton of money, but if you're in it for the long haul, $50/year for 2 years before the next halvening, then a 10X nets you $1,000 for living life as you normally would.
• Learn and earn - Some websites offer free coins if you learn about a specific Crypto for watching a brief video and taking a short quiz. Coinbase is probably the most famous for these. Personally, I've earned ~50 over the last year with this feature.
  As a note, I recommend immediately converting these coins to your favorite projects as the value typically drops dramatically after the L&E due to heavy sell pressure.
  CoinMarketCap also has a learn and earn feature, though it is more limited. The offers are region based, so you may be unable to participate. Either way, it is extremely easy to do and earn a few $.
• Crypto credit/debit cards - These are essentially cash back cards but paid out in Crypto. They are also great if you don't want to use a traditional bank. Popular options include Crypto.com, BlockFi, Gemini, and Coinbase. Most cards offers anywhere from 2-4% back and some have extra rules about what does and does not qualify for rewards. I like CB's debit card. The rewards change monthly, but they typically have a 4% back offer. Even at 2% back, it beats a traditional credit card most of the time.
• Airdrops- First, be careful with these. There are a lot of scams, so make sure you DYOR before jumping in. However, many chains and projects offer airdrops of coins or NFTs. https://airdrops.io/ is a good place to start to see if you'd qualify for airdrops with any of the projects you hold.
  
• Shopping rewards- This is different than using a credit/debit card (and often times these rewards stack). There are some sites out there that give a crypto rebate. Lolli and SocialGood are two that I've tried personally. They have a few problems like a long delay for the payout (90 days in both cases), but if I were going to buy the product anyways, it's a nice bonus.
• Play To Earn Games- Play games that reward you with crypto. Gala Games is a popular platform. Gods Unchained, Crypto Royale, Axie Infinity, etc all follow the routine. They games aren't great currently and require a lot of grinding to make any real money, but you might find a game you like.
  
• Publisher0X- This is a blog that you can tip for free between 20-80 % to you and to the writer. This is a really great site that has a lot of good knowledge (as well as some terrible blogs) but the tip incentive is great. Read and learn about crypto, and make a little bit every day.
