Airdrop farming is one of the ways I have used overtime to boost my crypto holdings and I can say the adventure is really worth it after getting over 5 different project Airdrop in 2023
Care to share those 5 different project airdrops that you got last year?
TBH, I didn't focus on airdrops last year because of personal reasons, and because of that, I missed so many airdrops like Celestia. Farming airdrops is proven to be one of the best ways to boost your holdings, but always take note that airdrops isn't 100% guarantee.
If you're joining on airdrops, always lower your expectations, and lower your spendings as well because there are some projects that they require you to make some interactions on their platform and in the end, you will not get incentivized.
When it comes to exchanges, launchpool has been my favorite way of earning by staking a certain amount of token for instance BGB or BNB to get some free token Airdrop.
I tried joining on Launch pool as well, and I only have 1 BNB currently, and instead of just being stored on Binance, I used it to farm MANTA, and ALT tokens. After that, I immediately sold my BNB to buy another staking coin. Launchpool has been giving out free tokens to those who stake their BNB's, but take note that the higher the BNB or whatever token they require you, the higher you will get. I'll just share that with the 1 BNB that I used to farm MANTA tokens, I only got 1.5 MANTA which is around 4-5$ currently.

After all, it's free so don't expect too much on it.
So am curious if there are other ways you guys have been earning without investing your funds.
Join a signature campaign, and use that earnings to buy crypto holdings.
That's what I've been doing ever since I joined signature campaigns that's paying me in BTC. I always use a portion of it, and buy different tokens. Without signature campaigns, I might not be holding any cryptocurrency right now.
