Confused, bitaddress.org generate 2 addresses

[moha sasa]

- Hello guys, I hope you're all ok.

- When I use https://www.bitaddress.org/bitaddress.org-v3.3.0-SHA256-dec17c07685e1870960903d8f58090475b25af946fe95a734f88408cef4aa194.html to generate a BTC address and search this address in https://www.blockchain.com/, it tells me that I have two addresses one for BTC and the other for BCH and both have the same address.

- What if I send BTC to a BTC address and found it is in BCH address!!??

+Thanks in advance.

Both BTC and BCH addresses are valid on each other's chain. So your BTC/BCH address X can be used to hold and spend BTC and BCH both at the same time. You just have to use a wallet for each coin.

If you send 1 BTC, you can hold the BTC and spend him by using a BTC wallet (e.g: Electrum).
If you send 1 BCH, you can hold the BCH and spend him by using a BCH wallet (e.g: Electron Cash).

Since blockchain.com explorer supports both coins, it sees the address as valid in both chains.

Either coin can be sent to the address you've created, but only use the address for one type of coin.  If you send BTC to that address, use it only for BTC.  Do not send BCH to the same address.

Apart from Bitcoin Cash wallet software being shady, i don't see any reason why he shouldn't be able to do this?

What security risk exactly in involved by storing multiple chains of coins on one wallet? (Assuming they have replay protection that is.)

Do not use blockchain(dot)com/info.

Their main investor is Roger Ver who's been attacking bitcoin for quite some time. He has been using techniques like this to confuse people and lure them to bcash.

Use this instead:

It does pretty much the same thing.

None that I know of, but I have never owned any BCH and don't plan to.  My recommendation stems from the assumption that the OP is new to crypto, and keeping different chains on different wallets may be easier for neophytes to manage.

if you mistakenly sent to a BCH address, your bitcoin will be arrived in that same address on BTC chain
whoever owns the private key of that BCH address can use the same private key to access that bitcoin
but just as TryNinja said, you will need to use appropriate wallet(s) to access them

For BCH: Newer services depreciated the user of "1" addresses of Bitcoin Cash and only accepts "q" addresses by deafult , there's an option for legacy addresses though.
Bitcoin: Bitcoin doesn't support "q" addresses and you wont be able to continue if you ever pasted a BCH address.

If ever you mistakenly sent your precious Bitcoins to a trash wallet, knowing the private key is enough to be able to recover your bitcoins.
Read the comments above for some of the examples.

To make it clearer, it is not possible. If you send your BTC to a BTC address and not mistakenly type a BCH address then you'll find your BTC on your BTC address. Even if your BTC and BCH address is the same, it still operates on different chains. So it won't show up suddenly when you check that address on your BCH wallet.

address reuse for one. broken implementation of cryptography related functions for another. it is not just about being "shady" it is about not being popular enough to be reviewed. no to mention that a lot of the times developers of these altcoin wallets are not competent enough to create a secure wallet. and leaking altcoin private key (eg. reusing k or using a weak k when signing) means you also lose your bitcoin.
