About Bitify I heard a few people complain about their issues using Bitify that until now haven't resolved but some people use it without any issues.

Check this similar topic Has anyone used http://bitify.com and what's the authencity ?

I agree with multiple outputs but I just want to add this based on the Bitcoin wiki the fee is not just calculated on the size of the output but also the inputs. Both of them shares the transaction size in total.

There are some calculators about this how to calculate the size of a transaction with a better explanation you can check the link below.

I never heard of the vkbit.com pool and according to Whois it was just created last year if I were you I suggest use a well-known pool like https://solo.ckpool.org/ or Viabtc pool.

You can try them and update here if still didn't work then post the logs of the unit here just don't forget to put the logs inside the insert code tag so that we can easily read them.

According to this "How to successfully complete the KYC process" if you intend to use hash-power market place KYC is mandatory or if you access your EUR wallet & EUR exchange it will ask for KYC.

And according to this "What is KYC?" KYC is not required but for previously registered users who are logging in for the first time after the launch of the new platform KYC is mandatory and it is required for account protection.

What is your purpose why did you access your old account again? If you are not planning to use the marketplace and EUR wallet/exchange and you just want to use their wallet and mining you can make a new account with email only according to this "KYC tiers".

I am also one of their previous users I never heard or even inform via email that they added KYC.

About the alternative, if you just want to sell your miner's hashrate then miningrigrentals is a good alternative without KYC.

What do you mean? Did you already send it to another wallet?

If you already sent the BTC to another wallet it shouldn't take long to transfer or send to another wallet unless the fee you set is very low or below the recommended fee suggested by mempool.space.

Is the issue or error came from LNBig? If yes then you should contact them why did you get that error?

I never heard of this site before but I tried to search and check their About page if they have contact info. It seems they don't have any contact info even searching it through Google.

Why would you use a third party if you can open a channel with Electrum?

What OS or machine do you run these miners on?
There is someone who has the same problem here on the forum it might be due to OS that causes this r909 miner unstable.

You can read the whole response by Kano here below

It also depends on your Electricity rate the s9j consumed 0.093j/Gh, s19j 0.036j/Gh, and s15 0.057j/Gh.

So for better efficiency then choose s19j if you have almost free electricity then choose s9j it consumed more power but if you have a very cheap electricity rate you can make a better profit with this unit.

For now, I can't find any alternative for OpenBazaar it's a marketplace to sell any products you want but I don't know if it is still alive.

Why not sell it for bitcoin here on the forum under digital goods and then hire escrow on this list "Recommended bitcointalk escrow services".

Next time if you are going to buy ASIC units to avoid scam sites like iceriver.io make a thread first here and ask if the site is legit or not before buying units from them.
Checking their reviews and research with your own is not enough the reviews that come from Trustpilot can be fake and the safer way to buy ASIC units is to buy directly from the manufacturer(If it's an Antminer then you can buy directly from Bitmain).

Have you tried my suggestion above?
Would you mind telling us what the backup wallet file looks like?

I don't know exactly what the Satoshi client looks like but I think the features are the same as the new Bitcoin core where you can open a debug console. If I'm right then check the help on the menu and look for debug>console tab then use this command to dump the private keys

Only use this if your Satoshi wallet has a password.

Then dump the keys using this command below.

Copy the dump key and import it to Electrum.

About cryptoassetrecovery.com I don't how safe they are but there is another well-known site that offers recovery services.
Here's the link https://www.walletrecoveryservices.com/ or contact DaveF for assistance.

The AI GPT wasn't designed for tracing a transaction or someone's Bitcoin and it can't also able to reverse or get the Bitcoin back to your wallet. For AI GPT it is an illegal activity.
I tried it on ChatGPT but it said they can't do that I don't know if GPT4 could do that.

Only law enforcement or cyber authority can able to help you with your problem they have a tool to trace them but if they already mixed the coins it would be hard for local law or cyber authority to find this scammer.

If you already did flashing the unit with different firmware stock or braiins or even HulkOS but the issue is still there then it should be a hardware issue. Have you tried to replace the hashboard or the chip sensor? If not, then try it first because without testing it you will never know if it's a hardware issue or software issue.

If the transaction is still unconfirmed I suggest import the backup seed from the blockchain wallet to Electum and bump the fee but I think it was already rejected from other nodes mentioned above it only shows on the blockchain but not on the other explorer. So if you move and import the seed backup to Electrum the old transaction won't show up and then you can create a new transaction just make sure this time change the fee higher than your old transaction or use the suggested fee from mempool.space.

Bitcoin mining machine is an ASIC miner(Physical machine) you can buy this on Bitmain or from other ASIC manufacturers and you don't need to worry about how to set up them because it is easy to set up and the guide can be found in their manual.

If you want to know more about what is ASIC check this link below

There is no instant profit in mining it all depends on your current electricity rate.
And there are no scammers that will tell you they are not legit or they are scammers.

That's pretty bad do you know where your coins came from or what exchange you bought them?

If it was from the 2012 exchange and the exchange is already gone then you have zero chance to provide any documents and to unblock your coins.

Would you mind to tell us what exchange your BTC came from?
And maybe we can find some contacts who runs that exchange before.

And I'm sure Bitmart is interested about deposited $100k because it's big money. I think almost all exchanges have withdrawal limits you might already reach the maximum limit that cause this issue you can maybe avoid it if you gradually withdraw them to small amount of $10k or $5k.


If you are fully verified there I suggest open a lawsuit against them or report it to SEC here https://www.sec.gov/tcr

Do you mean the private and secret starts with xxxx? If that's the first character it won't work if you import it to other wallets.

I don't have much idea what Satoshi wallet GUI looks like but instead of using Python to backup the wallet would you mind to check the Satoshi client on the GUI if there is a backup button?

What I guess is that the first transaction is $1000 with RBF enabled and a low fee since the current mempool right now is a bit congested and a few spikes recently paying 1 sat this TX will be stuck on the mempool and the other $100 transaction can be also a trap.

Would you mind to tell us if the $100 is confirmed better check it directly to the blockchain? But if not then the $100 is another trap same as the first transaction.

What are you dealing with the sender? If he promises that they will give you BTC worth $1000 with a bonus of $100 it's a sign that the sender is a scammer.

If you are living in a country with very cheap electricity why not buy a miner and mine as your passive income?

Staking is not good for the long term most of the POS coins are dropping fast compared to BTC.

Another passive crypto income that I think is building a WordPress blog and keep creating articles related to Crypto and do SEO to promote the blog. Once you gain a good amount of traffic you can add some ads that pays in Crypto like A-ads.
It is way safer than investing in POS coins.

There is no win percentage it depends on luck and difficulty and the calculators only calculate your daily Bitcoin earnings whether you win or not.

There is a formula that you can use to manually calculate your Bitcoin earnings.
Check this formula below.





You can exclude N if you only want to calculate daily total earnings.
