securing your Bitcoin holding and avoiding anything that will lead to your Bitcoin getting into the wrong hand is as important as avoiding buying and holding some altcoins. What shall it profit you if you become reckless while buying Bitcoin and you refuse setting up means of protecting and ensuring that you avoid links that's going to pose a threat to your holding?
When holding bitcoin, make sure you do everything possible to protect your bitcoin. It won’t really make sense to hold your bitcoin for years, and then at the end you will end up losing it to scammers, so it’s just better we properly learn about wallet security when investing, that's one of the first things we are supposed to know.
As long as you're in for the long term, you have to avoid doing even airdrop because that's one of the easiest way scammers are currently using to steal people's coin.
If you are holding bitcoin, that won’t stop you from participating in airdrops. I know lots of airdrops are created just to scam people of their money, some of them will ask people to connect you their wallet to their website, which they can steal from people that do that, but the best thing to do when participating in airdrops is to have a different wallet for airdrops, don’t make use of the wallet in which you have your investment, a new wallet should be created for airdrops, and make sure you don’t have anything in the wallet.
