Firstly, there are some airdrops that require bridging and many other stuff that also require fees, which means some of our crypto will be used on fees and coins that get bridged. I do have to warn you that do not rely on this all the time, cos if you are newbie, you won't know that airdrop will be worth it or not.
Airdrops to me are gamble games, if you’re not ready for it, then reduce the much hope you have in them in making you millions. Airdrops do pay but you can’t know which will pay you, so it is important for you not to be too hopeful in them to avoid disappointments. Those airdrops you need to pay some money to are seen as reliable ones, but I still don’t feel comfortable with them. In order not to lose funds and not get anything in return, just don’t pay to get airdropped tokens.
Now comes second, the most popular option, staking your crypto. There are tons of staking platforms you can search... But to be safe, DYOR on it. The staking can be done on Launchpool on Binance, PoolX on Bitget and many others.
Staking is a very good one and these that engage in them mostly do benefit from it. This is the crypto world though, you have to be careful in anywhere you want to put your money. Do your own research and only believe or invest at your own peril. You can hold anyone responsible for your mismanagement of funds by putting your money into the scammers den.
