so my address in btc wallet can possibly be other people address in the universe of bch? or btg?

no. if they have the same address on other chain they can also access your btc fund and steal it
like I said earlier, if that happens it is called collision

even thought USDt and bitcoin are not the same, but as a new user, this confuses me alot, why the address can be recycle by other coin.

if it not, will it be recycle and used by other people?
earlier you asked this in context of bitcoin and not in general cryptocurrency
your definition of recycle is not appropriate in lieu of reusing the same address when talking about 2 different chains
BTC and all its forks BCH, BTG, BTX, BCD, SBCD, and etc etc etc all have exactly the same valid address space

what if somebody should send me btc, but they send me usdt instead. and he show me the transaction already confirmed. i can be fooled easily.

as simple as checking the txid on the correct chain,
check BTC explorer (or your BTC wallet) if you expecting BTC... not USDT explorer

yes sorry, i asked in context of bitcoin. but i cant waste this opportunity by opening a new thread and ask another person.

USDT is a token on the OMNI network, which sits on top of Bitcoin... refer here: http://www.omnilayer.org

Basically, it adds extra payload to Bitcoin transactions... And, obviously, as it is using Bitcoin transactions, it uses Bitcoin addresses...

It's like all the ERC20 tokens on the Ethereum network... They all get sent to/from Ethereum addresses.

So, the address isn't actually being recycled by another "coin"... It's just a slightly different use-case of the existing Bitcoin address and blockchain... with a "token" thrown on top.

And, if you think that's confusing... Wait until you read about what happened with Bitcoin and Bitcoin Cash after the fork... (before BCH devs finally came up with the new address format) Tongue

Let say i have a wallet at blockchain.info, and deleted one address.

as I remember when you delete an address from listed addresses in your bc.info, it goes to archived addresses
you can restore it anytime to reuse it for receiving or sending in case some mistakenly send to that address
bc.info is an HD wallet now and generate new addresses deterministically from seed
as long as you have your seed (Mnemonic phrase), you can use it to restore all your addresses

is it possible to get the same address?
if it not, will it be recycle and used by other people?

for someone else? slim to none. if it happens this is called an address collision
address is not assigned, there's no such thing as recycled address

take a look at this

oh, we cant?

i always read about bitcoin safety on blogs, most of them advice to not use the same address over and over again for privacy concerns.

based on that, my assumption will be that the address in our wallet can be deleted for new address.

so we can create unlimited address within our wallet?

ps:unrelated. is yahoomessenger is still available? kinda miss the old time.

You can (reuse) and that's often what I do as well. It doesn't compromise your security, it's just not recommended, by design, to protect your privacy. There are some very good situations where you'd need to reuse an address (for me, it's to prove ownership or some base of identity).

As mentioned, in your wallet it would be deleted from your view, but not actually removed from your wallet or your control. That's just an interface.

Addresses are not unlimited but for practical purposes, as Xynerise points out, there's just no way anyone would ever run out of addresses.

It's not deleted, it's just not shown to you so you won't reuse it.
However if you send bitcoin to a previously used address your wallet can still access it as long as you still know the 12-24 word phrase you were given, you can import that to any wallet and still access your bitcoin from there.

Even if you use 20 different addresses a day, you still wouldn't be able to exhaust the addresses generated from your seed phrase in 10 lifetimes.

I didn't realise you could delete an address from that wallet. But even if you could, that would only be a cosmetic change - you basically will always be able to access any funds stored in any address in your wallet. And no, it's not possible for it to get "recycled" or used by other people. That's how Bitcoin works. Every address generated in your wallet is unique only to that wallet, since they're derived from the wallet's public key and accessible by its private key.

Therefore, the addresses are owned only by you... as long as you're the only one controlling your private keys.

You should still be able to use the old address since Blockchain.info generates new addresses from you wallet's xPUB. A lot of people who participate in the signature campaigns use Blockchain.info and it seems that they don't have any issues with reusing addresses. Nobody else will be able to use this address. Anyway, consider switching to Electrum, you won't have to trust third party to keep your bitcoins safe.

#Edit: buwaytress was a bit faster than me, I'll keep my post since it might be also helpful.
