Well, freewallet is basically an exchange pretending to be a wallet. Even worse: they tend to let little transactions slip by to give the impression they're a wallet. But then, by using some sort undocumented and undisclosed algorithm, they freeze your account when you withdraw a lot at once. You're not in controll of your keys, so you're not in controll of your funds.

The good news is that they are quite active on this forum, and i've seen loads of people that were willing to jump trough freewallet's hoops getting their funds unlocked eventually... The timestamp on your mail also indicates that the last conversation with them was yesterday.

Their account manager will probably enter this thread pretty soon.

One word of advice: once you get this mess cleared, move to a real wallet... Since it seems you're holding >0.7 BTC i'd suggest a hardware wallet (i have both ledger and trezor products and i can say i'm happy with them). For ~€100 you'll be in controll of your own keys, nobody is going to push some KYC BS on you again when you want to move funds from your hardware wallet...

That offer is just as valid today as it was a couple months ago

Basically, if you're somebody i know and trust i'll lend you as much tBTC as you'd need (within reasonable limits) without collateral or interest. If i don't know you and you have a legit usecase for the tBTC i'll lend you as much as you'd need without interest but i still require enough real BTC as collateral to re-mine the tBTC in case you'd default PLUS something extra to give you an incentive to return the tBTC instead of using me as an easy way to have somebody mining tBTC for you. If you don't default you'd get the collateral back (minus transaction and escrow fees).

I haven't looked at the testnet diff in a couple of weeks, but the block reward did halve, so if you're interested in loaning tBTC as a newbie/junior member, i'll have to re-calculate the required collateral.

I know some have criticized me for asking collateral, but if i'd lend out tBTC to newbies without asking any collateral, i'd end up with an empty tBTC wallet and i could just shut down my faucet altogether. tBTC is worthless, but that doesn't mean it's free to mine, so if i loan out tBTC and you default, i need some real BTC to mine tBTC to replenish my faucet's wallet...

The fixed supply is simple, more info can be found here: https://en.bitcoin.it/wiki/Controlled_supply
On that page, look at the table in section "Projected Bitcoins Long Term" and you'll see how a fixed supply is created by the halvings.

As for negative effects: it is hoped that by the time the block reward is close to 0, miners will mine for the sum of the fees of the transactions in the block they solve. It's possible some miners won't be able to mine profitably and turn their ASIC's off... It's possible the diff will drop... We'll see


Not really my area of expertise. But a whale is somebody with enough cashflow to disrupt the unregulated market. Basically pump a coin by buying a lot of it, pump the price upwards, then dump their bag while the price is high.
Can't really give you more info about this subject tough... I'm not a trader

A quick glance at the first week on the spreadsheet leads me to believe you are correct.

I joined @ week 10... DarkStar_ and Chipmixer never missed a single payment (unanounced), i'm still thrilled to be a member of the team... I already used 3 different payment addresses (a p2pkh, an embedded segwit and now a native segwit) so i have no clue as to how much drinks they've bought me for doing something i like to do...

Thanks guys, it's really appreciated

I'm just brainstorming/spitballing ideas here,  but maybe you can use it as some kind of site to provide information about fake ico's, scams, joke projects,... Since toiletpapertokes was, in fact, a joke, using your site for such purposes might be fine.

If you keep on adding useful content and build some loyal traffic, you might even publicize some clean, fact-checked ads to monetize your traffic.

You should be OK... I've seen studies and they all come to the conclusion that after 72 hours out of the body, the virus particles break down and are no longer infectious (even in "normal" ideal conditions and on "normal" ideal materials...).

If you buy a miner, i'd just accept the package from the carrier, place it in an unused room for 72 hours (wash your hands after accepting the package, make sure you don't touch any doorknobs with "potentially dirty" hands) and only open it once those 72 hours are over. Do NOT place the package in the freezer, as this will protect the virus.

Placing the box into direct sunlight for a couple of hours is also a good idear, as most coronaviruses don't survive uv ratiation.

The only downside is that you cannot check the package for damage as soon as you accept it, this might be a liability problem. Maybe talk to the seller/shipment company first and make sure they understand you won't check the package for damage the first 72 hours after receiving it.

PS: i'm not a doctor. I have a master in sciences so i do think i can understand how to read standard studies, but i'm not specialised in this stuff (anymore). I'm just telling you what i would do if i was faced with this issue. If you want to be 100% certain, you should contact your governement.

As soon as you deposit your USDT from whatever wallet you're using to the exchange, it's in the exchange's wallet.
The exchange creates some kind of virtual wallet for you, you no longer hold any USDT (the exchange does). You just have a record in their database crediting you some of the USDT they hold in THEIR wallet.

If you exchange your USDT to BTC, you'll have a new virtual wallet with the exchange, now with BTC credit.

If the exchange is honest, they'll allow you to withdraw your BTC to an address generated by a wallet of your choice. At this point you'll have BTC in a wallet where you controll the private keys (hopefully), so now it's your BTC.

I don't really understand why you'd be forced to sell your BTC back for USDT here...

I'm afraid i'd have to agree...
7 letters, hypen, .de tld, no history. The resale value is close to $0.

However, i've bought domains in the past myself (not going to disclose them, since not all of them are whois protected) and i do think that if you're going to invest a lot of time and effort into your blog, any domain can be a hit, it's just the domain name itself being worth nothing at this moment.

You are right, as soon as your private key touches a device that's been online, you should consider your paper wallet to be compromised.

If you have multiple unspent outputs funding the address on your paper wallet, you should use them all...

Make a new paper wallet, import the private key of your paper wallet into electrum (for example, do check electrum's signature before using it, download only from the official site), create a new transaction spending all unspent outputs, pay whoever you have to pay and send the change to the NEW paper wallet.

If you're really security-contious you can even use an airgapped setup: create a watch-only online wallet where you import the ADDRESS, create the transaction spending all unspent outputs funding this address (change going to a NEW paper wallet that was created in a SECURE fashion), then install electrum on an offline machine where you import your private key, transport the unsigned tx from the online machine to the offline machine for signing, and back to the online machine for broadcasting.

I'm having a meeting right now, i'll try to answer any extra questions in ~0.5-1 hr.

Ok, 6 characters is a LOT less impressive... That's what i did with a simple cpu vanitygen in a couple of hours aswell when i generated my vanity address in the first place... If i would have had a couple GPU's it would have been done in far less time, so matching 6 characters proves very little.

Mistakes are possible, but this does come over as somebody being called on a bluff... First telling us you have the private key for an address matching the first 13 characters, but when being called out only being able to produce a pk for an address matching 6 characters does sounds a bit fishy, don't you agree?

If you want a vouch that you indeed have a rainbow table of private keys => addresses containing 10% of the address space, i propose the following:
I generate 500 addresses, completely random, and post them here. You run your algo against these 500 addresses, and if you're able to find between 25 and 75 of the private keys which public key hashes are equal to the addresses posted in my list, i'll give you a vouch which you can use when you're trying to monetize your service.

13 characters is already quite a lot, but defenately not enough to backup your claim of having a rainbow table with 10% of the adress space's private key... But still...
I didn't see any real proof tough. Everybody can claim they have a private key.. Please sign this message with the private key belonging to the address that starts with 1MocACiWLM8bYn


By the way, your OP was quite hard to read, i take it you're not a native speaker... This isn't a problem, but you're throwing all kinds of numbers around... 84.000.000.000, 12.000.000, 21.000.000...

Even if you have a database with 84.000.000.000 private keys next to their public key hashes's, the total address keyspace is 2^160.
84.000.000.000 is far from 10% of 2^160.

In reality, even if you have a rainbow table with 84 billion records, that's only 0.000000000000000000000000000000000006% of the total address space...

Well, it's either an april fools joke, a scam attempt, or somebody that scanned 0.00000000001% of the address space and thinks he has any chance of finding a private key of a funded address... Or we're dealing with somebody from the future that's running a cluster of quantum computers.

But ok, for the sake of the forum, i'll bite:

Now, encrypt my private key with my pgp key found here: https://keybase.io/mocacinno/pgp_keys.asc
them PM me the encrypted private key.

If it's correct, i'll vouch for you... If not, i won't... I *might* even declare this a scam attempt...

I will not send you part of the private key, i will not sign anything that's not drafted by me, i will not open any website, i will not install any app,... As a matter of fact, i'll ignore any message you send me,  you claim to have a rainbow table, let's see if that's true.

@realdawgguy, you only made two posts, the second one does need some clarification


Did you mean you filled the address you imported? Like "Funded" this address, send funds to the imported address you scanned from a barcode on the internet???


or, as nc50lc already asked:
In this case, you might be in trouble... You created a watch-only wallet by imported the address. You cannot spend any funds that are funding said address since you don't have the private key. Any funds sent to the address you found on the internet are only spendable by whoever generated that barcode (if he still possesses the private key).

If you did this, start by saving your browser history and find out where you found the barcode. Maybe it's an example barcode and the seed, xprv or private key is printed in the vicinity? Maybe there's an owner you can contact and explain what happened (if he's an honest person, he might reimburse you).

I just hope this worst case scenario isn't the reality...

There is (yet) another reason why people would keep on mining even when it's unprofitable as long as they BELIEVE the price is going to rise again (or the diff is going to drop).

If you own a big mining farm in a western country (>1000 ASIC's) you most likely need a staff of 3 or 4 people (guys that have crypto backgrounds, guys that have technical backgrounds, security,...). Next to this you're renting a serverroom.

Your fixed costs each month include (guesstimations):
A writeoff of your ASIC's (€60.000/month for the ASIC's since i estimate they need to be replaced at least once every 4 years, and they cost > $1000/piece)
A writeoff of other equipment
A fixed wage of your employees (4 employees @ €5000/month = €20.000/month)
A fixed cost for your serverroom (€100/U/month. 4U/ASIC=  €400.000/month)
The fixed cost is almost €500.000/month in this fictional example. This cost remains the same whether the owner is mining or not...

Offcourse, at these costs nobody could ever run a mining farm anymore... Most mining farms probably have less employees, or use crappy serverrooms instead of professional. The main point still remains tough: even with few employees and a crappy serverroom, you'll have fixed costs (the writeoff of the ASIC's for example)

These are fixed costs. The premise of this excercise is a western mining room owner that is currently mining at a loss, but believes it's only a small dip. If he turns off the machines, he might get some discount from the serverroom owner since he's no longer using power... But he'll still have to pay for the writeoff of the ASIC's, the writeoff of the other equipment, the employees and PART of the cost of the serverroom.
If the income he gets from mining is bigger than the discount he gets from the serverroom owner, it's better to keep on mining at a loss, since the net loss will be smaller than stopping altogether.
And it doesn't matter if i grossly overestimated the costs, if it's a one man operation,... There are always fixed costs and variable costs. The variable costs decrease when you turn off your ASIC's, the fixed cost remains. As long as you mine more than the variable costs, it's a good idear to keep mining.

Do realise that this situation can only exist if the owner of the farm believes it's a temporary dip in price, and if he has reserves or can get a loan. I know there are also countries with almost no protection for the employees so it's easyer to fire them over there...

Well, miners don't set the price.

Bitcoin price is just supply and demand (and manipulation). If a miner can no longer mine while remaining profitable, he can:

• Stop mining, sell his hardware
• Stop mining, keep his hardware in case the price goes up or the diff goes down
• Keep mining at a loss, hodl the mined BTC
• Keep mining at a loss, sell the mined BTC

There is no way to know what the actual mining cost is... Some miners in China have big "factories" and pay pennies per Kwh, have a direct link with the ASIC manufacturer (without customs charges or big shipping costs) and pay their workers only a fraction of what a western worker would cost. For them, the actual "cost" of one bitcoin is pretty low.

Compare this with a miner in my country, where the power costs 0.27€/kwh, where you have to pay big bucks to get an ASIC into the country, where the minimum wage is >1500€/month. For this miner, the actual "cost" is pretty high. It's only when the diff falls really low, and the odds of a 51% attack rises, the price can actually be influenced by miners. Offcourse, miners do have some indirect effect on the price: whenever they start a mining war, or decide not to mine 0 fee transactions, they push down the price due to the negative press.


So, it's basically the other way around: the market dictates the price, the miner decides if he can mine at the current price, or if he has to shut down his operation.

debug.log is the log written by default when using bitcoin core...
For electrum, you can enable stdout debug logging on the terminal by adding the -v argument.

@OP: depending on your OS, the path to the debug.log can be found on this wiki entry: https://en.bitcoin.it/wiki/Data_directory
The log does not contain your private key, nor seed... Nobody can rob you just by reading your debug.log, so from a security point of view, it should be safe to post it's content. However, by sharing the log, you might decrease some of your privacy

How much did you pay?

If it was in the >$6000/BCH range, you were scammed... If it was in the >$200/BCH range you were misleaded but not scammed in the strict sense of the word...

You can exchange your BCH for BTC, but you'll lose value, since exchanging requires you to deposit BCH to the exchange (you'll lose a transaction fee), then exchanging BCH to BTC (you'll lose the exchange fee), the withdrawing the BTC (you'll lose the withdrawal fee).

So, it seems slot #2 gets a second chance at claiming his/her prize, a 24 hour window to follow the procedure listed the first time a winner was drawn.

Well... Because of the problems i had, the final raffle was delayed for a week... But sure, i'll hold it one last time. However, this time i won't disclose if the raffle winner has claimed his/her price.  It's the final time i re-run the raffle, so there is no need to publicly declare if the winner stepped up or not. If there is a winner, i hope he/she creates a new, anonymous, account and posts a picture of his/her keychain after he/she receives it... But that's completely up to him/her.

If i have time, and if there's any demand, i wouldn't mind writing down my experiences in Theymos's original thread. He made a nice system that adds a big layer of privacy, and my experience would help other's wanting to benefit from my experience, but if there's no demand, i probably won't bother (but if there IS demand, i wouldn't mind doing a writeup)

So...  Let's roll one final time:
We're currently @ block #623 591
Let's roll with block number #623 593
