Bitcoin wallet and paper wallet

[Marcel28]

 Please i want to know if in my wallet i have one single address and  receive more transaction on my single btc address it is ok ?

I heard that is a bad thing to receive more transaction to single address, but i see on internet that some people want donation from people to single
address like paper wallet. Do you know if i have bitcoin core wallet with full synchronizing, and i have single address like receiving address, it is ok,
because i see that paper wallet have one single address and people that request donation have one single address. I look days to internet and i see a lot of help but i want to know more to be sure.


PS: I don`t want donation, but i ask because if i want to sell something to know if is ok to receive payment to one single address.

I can't barely understand what you are saying though, are you using an exchange wallet? if yes then you better get a desktop wallet so you can provide more address if you want.

I did a little as fast research about this paper wallet that you are saying and it stated that 'A paper wallet is the name given to an obsolete and unsafe method of storing bitcoin which was popular between 2011 and 2016. It works by having a single private key and bitcoin address, usually generated by a website, being printed out onto paper.' so with that being said I hope it answered your worry.

Receiving transaction to a single address was not bad and will never be, maybe for people who are doing bad stuffs, maybe it's all about of the sorting purposes because every addresses is unique and confusing when there are so many.

Firstly, after going through the OP statement i understand that he was not talking about an exchange wallet but his personal wallet and he want to know the reason and benefit behind using different address per transaction since paper wallet have a single address.
OP, if you use a full synchronized bitcoin core single address you're ok but the purpose of using another address out the listed addresses on your wallet is another way of been vigilant so that no one can track or know the amount of btc you're holding cause knowing your holding may attract online thefts.

Usually, users have a "public address" that they use for (yes) donations or for transparent payments/transaction that should be isolated from their Hot wallet.
You can easily make one using any SPV clients with "Import Private key" feature to make a single address wallet.

There's no alarming issue including privacy since its inputs will not be used together with the "private" addresses.

I heard that is a bad thing to receive more transaction to single address

It is not necessarily bad, at least for now. What makes it bad to some people are because it can expose your identity. This shouldn't be a problem if you're a merchant or charity foundation because you should never hide your identity (at least usually). So whether you change your address regularly or not, it depends on whether you want to stay anonymous or not, at least before there is a strong computer to crack your wallet with your public key.

Addresses should be used only once, that is how it was intended. Every time you receive Bitcoins and then click on the Receive tab in your wallet it will generate a new address. This is the best practice for your own safety and privacy. Using the same address allows third parties to connect that address to you.

I don`t understand, some people say it`s not bad thing to use single address, and some people say it`s not good to use single address.
If i use single address for one transaction, and 2000 people send funds to my address, i lost my funds, because i see that bitcoin core have 100 keypool

It doesn't matter if you don't care about privacy. If you care about privacy, you can make as many public addresses as you want.

You don't lose funds, they are still in the same wallet.

A SINGLE wallet can have (nearly) INFINITE addresses.

PAPER wallet is irrelevant, with the private key (seed words) you can generate more addresses.

If you have no privacy issue, you can receive as many as transactions you want in a single address. People use more addresses so that they don't get traced. If you have to have hiden yourself, you can use Bitcoin Mixer.

But with keypool, what is this keypool for, and what means 100 in bitcoin core ?
And what is if i have in my wallet 2 address and i backup my wallet, and then i import my private key, or i put backup in my wallet, and i lost my funds because i see on internet that is 100 address that they isn`t used and when i put my backup or import key in the wallet, the balance appear 0 because that 98 address is not used, and was used only 2.

[Marcel28]

Thanks, but i read on internet that keypool is for like when i receive bitcoin from 100 people, and if is set to 100 and i receive 101 transaction, i lost that 1 transaction because is set to 100. Because if i have one single address in my bitcoin core wallet, and  that receive transaction is keypool, because every transaction have a key and any transactions is like key and is set to 100. Thats means i can receive only 97 transaction(send or receive). Is true or not, i want to know ?

[khaled0111]

That is not what key pool does. The number determined by poolkey defines how often your client has to generate a new key and how often you have to backup your wallet.
If you use a HD wallet, you don't have to worry about anything related to key pool.

but i read on internet that keypool is for like when i receive bitcoin from 100 people, and if is set to 100 and i receive 101 transaction, i lost that 1 transaction because is set to 100

If you use the same address to receive those transactions, you will not need to use any of the 100 in the key pool. Which is not the case when sending bitcoins because you will need a new pre-generated key to use it to collect change.

If i use single address for one transaction, and 2000 people send funds to my address, i lost my funds, because i see that bitcoin core have 100 keypool

if you have 2000 people sent funds to your single address, that means you have an address with 2000 transactions
in other word, you are reusing the address for receiving payments... you will not lose any of them
100 keypool means you have 100 pre-generated addresses ready to use
but in your case you just use 1 address out of 100 available addresses

I don`t understand, some people say it`s not bad thing to use single address, and some people say it`s not good to use single address.

it's somewhat a bad practice because by reusing the same address you are losing your privacy
