Tons of random free coins in my ledger?

I loaded up at the bottom of the bear market from June 2022 to June 2023. Threw everything onto a ledger. Haven’t touched it since.

Opened the thing up this week and there are literally hundreds if not thousands of free coins by various names in there now.

I assumed airdrops.

But I heard something about some of these being scams. If they’re in the ledger, are they safe to redeem?

Or is the scam that you have to download their Wallet app and that software is basically going to clean out my balances?
