If you're like me, you've been collecting free 'Candies' on CoinGecko for ages without having anything to spend them on. Happily a couple of new rewards have appeared on CoinGecko recently, one of which is the "Baby Doge x CoinGecko March Madness Giveaway".
For 300 Candies, you can enter a raffle to "become one of the 10 lucky winners to win a prize pool of $2,500 USDT". It doesn't specify what the prize is, but you have to give an ETH address so that might be a clue. (Baby Doge is actually on Binance Smart Chain but the addresses are interchangeable - for example my BNB BEP20 address in Trust wallet is the same as my ETH address.)
OK, the odds of winning are quite slim, but 300 Candies is not a lot of Candies - you can collect 310 a week just by logging in each day and clicking the 'Collect' button:

I also have a soft spot for CoinGecko's Rewards, having picked up quite a large chunk of ACS (Access Protocol) in an airdrop last year. You should always DYOR (Do Your Own Research), but any scheme vetted by CoinGecko is much less likely to be a scam.
Taking part in the Baby Doge raffle involves a few steps, but nothing too confusing:
1. Log into CoinGecko and go to Rewards (https://www.coingecko.com/account/rewards)
2. Click on Baby Doge x CoinGecko March Madness Giveaway
3. Click on Redeem Now

4. Go to My Rewards > Active Rewards (https://www.coingecko.com/account/my-rewards)
5. Click View

6. Scroll down and copy the voucher code - you'll need it in a second
7. Click Use Now
8. Enter your name, email address, voucher code, and ETH address in the form that appears

9. Click Enter Giveaway
You'll now be taken to a page where you can complete different actions to earn entries. If you don't want to use your socials or sign up for anything, click on 'Visit Baby Doge Swap Page' which will give you one entry.
Personally, I visited the swap page, followed on Twitter and joined the Discord server - but I didn't join the Telegram (because my number's been banned - a story for a different day!). That gives me three entries:

The draw runs until 6am Eastern Time on 29 March - best of luck if you do take part.
