Your advice is good for beginners but I don't recommend that you share the same ETH/BSC address to many airdrops, those are the ones that have your coins and you use them personally so it's best to set up a dedicated wallet for each BSC airdrop and choose the best one for ethereum one.
This is true OP. If you are fond of airdrops. Used your wallet assigned for that. Segregate as much as possible the wallet for trading or own personal wallet from the airdrop addresses. Its important also to protect yourself from such scams or lousy scammer targeting wallet for money or hacking. This is inevitable so must be cautious at all times. Dont let scammer connect into your direct funds via airdrop.

Using a trust wallet may be appropriate, but it is closed source, so it is better to use an open source wallet like NEW wallet[1] or MetaMask[2].
Using the wrong address may not mean that you completely waste your money, and you should not share your private key with anyone.

It doesn't mean only on trust wallet both of ETH and BSC will be same, it depends on the private key. A same private key will generate same address for ETH and BSC on any wallet support that chain.This is why I like metamask wallet, it supports all available chains in crypto space either ETH BSC Matic RSK and others, just drop your same ETH address and you are set, to see your tokens you only need to change the chain networks, easy as ABC.
You need to add those chains to Metamask first, otherwise you can't use it and prevent from lose (sending to wrong address). Configure the wallet, click add network and fill the information about specific chain you want to add, you can googled it.
