dkbit98 wow bitpay can be self hosted, I'm a huge fan of that, and it supports XRM and LTC which is also pretty awesome!!
Thank you a lot, currently this looks like the best solution.

And thank you for all the other responses as well Smiley

Hello guys you have been very helpfull over the time, so here i am again:

So I am looking for a payment provider that accepts BTC and Altcoins
(LTC, XRP, ETH ... maybe XMR)

These are the requirements:
1. Payout in BTC (so convert altcoin to BTC)
2. Accept clients from offshore countries (Bahamas, Seychelles etc)

Coingate got pretty close, but they do not accept clients from dubious countries.


Thank you very much in advance. Smiley

@PawGo do you request 10 address every 2 seconds so:
A) 1 request with multiple addresses
or B) 10 requests with one address each

@NotATether that is awesome

@HCP you are right this is limiting, but relying on an api to check balance isnt that bad.
for the beginning i am ofcourse looking for a free solution. but i have no problem paying once my shop gets profitable. Im justing trying to reduce the upfront cost.

I think @NeuroticFish 's solution might be the best, I think 5 requests per second might be enought. I am not too optimistic Cheesy

Hello community,
I am looking for a api exactly like this one:
https://blockchain.info/rawaddr/1DEP8i3QJCsomS4BSMY2RpU1upv62aGvhD
All I need is the "total_received" :/
sadly my server ip gets banned after a few requests.
Any alternative?
If you suggest a selfhosted solution it has to run on win and linux.

PS: I cannot run electrum or download the whole blockchain.

Rather than "sweeping" the private key periodically, it would probably be more convenient to create another electrum wallet using that private key.
1. Select "Create new wallet" or "New/Restore".
2. Name the new wallet.
3. Select "Import Bitcoin addresses or private keys".

thats a good idea, but if i want to send the bitcoin i still would have to pay the "high" transactoin fee

How did you arrive at your numbers? What wallet or service is recommending you pay such a high fee?
buybitcoinworldwide.com but the fee drops each time i check, and only for 1 block confirmation.
I guess ill just put 1sat/vbyte and wait. I dont care about the time.

You just display the users an invoice which is generated by your Lightning wallet and they pay that invoice. The money will arrive to you in seconds and no confirmations are needed.

I don't understand what you want to sweep. If you want to get the Bitcoin out of your Lightning wallet you can send the funds to an on-chain address of yours through a chain swap service like https://boltz.exchange/.

I have some limitations: server cannot store private keys, programming is in c#, every Bitcoin holder should be able to pay, not just lightning user, has to rund on windows and Linux.

This is wrong. The transaction fees depends on the ferrate at a particular time as well as the size of the transaction. It has nothing to do with the value of the Bitcoins being transferred; would be quite absurd to pay $100,000 for a $1 million worth transaction.

I understand that, but if each address holds 10$ of Bitcoin, and for each new address/input added I pay 5$ fees (because fees are proportional to the transaction weight) it is equivalent
 to 5% (current fees)

The transaction time doesn’t really matter, if it’s 1 week I don’t care.


Is the lightning network usable if you only have the private key to the individual Segwit addresses? Is there a function like sweep from electrum?

Hello forum,
Let’s say I have a shop and sell items ranging from 1-10$ how do I efficiently accept that?
If each user gets his own address (which is kinda necessary) and I want to transfer the funds from 1000 user, then I would have 1000 inputs which makes the fee incredibly high.
I calculated already with an online fee calculator, and the transaction fees currently would be ~10% of the actual value. Is it possible to send without any fees? Or less than 1sat/bit?

Greetings glsck

When you receive bitcoin to an address/public key, in order to spend that bitcoin, you need to use a private key associated with that specific address to spend that specific output. When you sign a transaction that spends your bitcoin, you are signing that you are spending a specific output to a specific transaction.

For example, if you receive a transaction to address bc1abc123...3 that is the 3rd output to txid 34def...45, you must use the private key associated bc1abc123...3 that signs that you are spending the 3rd output to txid 34def...45.

Thanks for explaining the obvious, but that was not the question. Cheesy
The question was refering to receiving on a address (public+private key pair) which already has been used as output.

Re: Bitcoin mining is not profitable enough!

@NeuroticFish Thats a good point. But what @ranochigo says is much more valid. If the block reward is "only" 6000$ per block, and a 1Million dollar transaction could be forged for 100.000$ worth of mining equiptment and electricity the transaction cannot be trusted. But maybe its a good thing, that in the future big transaction cannot be trusted.

Half of the network is probably now secured by $10k a piece machines that would blow the circuits in a lot of houses when plugged in yet we're facing a threat of centralization because of the $200 2tb ssd. Really?
In my understanding its the mining pools that have the control so there are already 5 Pools that control over 50+% of the hashrate. So it doesnt matter that the pool itself is decentralized.

@franky1 your point "a" makes no sense, but "b" and "c" are valid.

This sounds like a good plan except that is it not true that the direction of development now is on layer 2 rather than on chain? I think the size is still a problem so they would like to restrict it on chain like that and keep those 100k transactions all on Lightning.

It will probably end up being no fees, but rewards being worth much more thanks to price.

It seems like you and Wind_FURY are the only ones that understand the problem, everybody else is just closing their ears and screaming: BLABLABLA THERE WILL BE NO DOLLAR EVERY DOLLAR COMPARISON IS POINT LESS
But fail to understand it doesn’t matter if it’s written in dollar or btc, I could write the transaction fee in potatoes…

There's no guarantee that $ would still exist 200 years from now or that it would still be the global currency …
It’s about buying power. You have to use USD for this comparison NOW because it has consistent buying power. Bitcoin doesn’t. Usd will only be replaced buy something similarly consistent. If you get your paycheck and the next week you have half the buying power (like with btc) nobody will adopt that.

What if each block contains 100000 transactions instead of the current 2800, little infrastructure change is probably needed to change that (if any other than code and signalling). Each of those could pay $1 and overpay on the current system.
The is a problem with that already and you know it (Blocksize). Bitcoin isn’t made to last forever, and I am just now thinking about the future.

Yes but my point is it doesn’t matter what the fee is in btc. If the fee would still be 0.000030BTC in 2121 but the fee alone if worth 100$ then you would not be willing to pay that. So it only matters what the fee is in $.

Just to clarify:
I will refer to an address as pKey.

I have this scenario:

Bob sends money to Tim
txIn ——txOut
pKey1->pKey2
0.5———>0.5
Now Tim sends his cash to Hannah
txIn ——txOut
pKey2->pKey3
0.5———>0.5

But Tim receives again money from Bob (to the same address)
txIn ——txOut
pKey4->pKey2
0.5———>0.5
Can he now spend 0.5 btc with pKey2 as input?




Second question more important one. (That’s the reason I’m asking the first one, so I can understand better)
Let’s say I have a address, on this address I received 0.1 btc daily.
Now I am using electrums sweep to transfer the funds to my real wallet. Will I be able to do indefinitely, meaning keep receiving 0.1btc/day on this one address and then using electrums sweep to transfer the funds once a week to my wallet?
