I want to know more about Wallet address poisoning

[nakamura12]

Well, if you haven't know about it then it is all about sending your address a coin, token mostly if it's in network like bnb network and eth network. Some of my wallet address contains different fake crypto and if you fall for the trick then you mostly just spend money for nothing. Well, in bitcoin network is that I never heard bitcoin being attacked like that but as others have said that it is very common on networks like eth, bnb and similar network.

poison a wallet is when they notice that you have funds on your wallet.

More effective on recent transactions.

Basically, any people who are doing transactions on the chain will get a poisoned attack because the smart contract reacts to on-chain recent transactions and could be specific amount transactions so they can get a bigger target amount.
Since most people already answer the question, just answer number 4. Yes, but hacker love to use (Faster Transaction Speed & Cheap Fee) bitcoin are to heavy and costing a lot resource for setup the attack. That's the reason, why bitcoin are not really getting targeted by hacker.
