You are a cryptocurrency user but not careful about your crypto wallet; it sounds unrealistic to me. I won't leave my crypto wallet for scammers. I don't have any faith in Airdrop, and I can't risk my wallet just for a few pennies. Once upon a time people earned a lot from airdrops, but nowadays all these airdrops are just scams. They don't distribute tokens; even if they did, it's just worthless tokens.
Projects nowadays just think about raising funds; to do this, they are running airdrops, etc. But actually they don't care about investors or contributors. If you really feel you can make money from airdrops, then just use an alternative wallet instead of using your main wallet. I won't trust any third-party apps or add-ons to protect my wallets. If I can't secure my wallet myself, then how would a third party protect me?
Gone are the golden days of airdrops. Although some would still find it profitable, but majority have avoided it already. And not to mention those scammers that are hiding on the shadow of airdrops, so if we can avoid them, then it will surely lessen the risk that our crypto wallets are exposed to.
It would be best practical if we shift and focus into bitcoin. At least there is higher assurance that with bitcoin, greater profits are also waiting ahead, provided that you won’t risk your wallet into some third-party applications.
It is always good you store your airdrops on a different device to avoid your wallet being hacked, just like the mistake you did, thanks we're smart enough to have noticed that something has gone wrong. The security of our wallets are very important and so full care and concentrations must be put to place for our wallet safety, if not we end up losing all we have worked for within a short time frame, and that is why you stay out of links, apps and websites that are not that important to you.
The security of your Bitcoin wallet is in your hands, therefore you need to protect it from any harm.
In terms of profits, airdrops can't be compared to Bitcoin in any way, as a Bitcoinner, I see no reason why one should be engaged in air drops because there are a lot of unsecured and untrusted projects .
