The links there seem to do the trick...

For example: https://bitcointalk.org/index.php?topic=211858.msg2221664#msg2221664
explains it pretty clearly

I'm not a multibit user myself, but i did try it out in the past... Personally, i'd suggest you to move to electrum if you want more coin controll options (like importing private keys from other wallets, re-using your addresses, picking your inputs, chosing your fees).
I say this because, after testing multibit HD, i did not find a way to do the things you ask (importing private keys, coin controll or address selection).

In my personal opinion, after a really quick testrun, i found multibit to be a great wallet, but it shields its users agains some of the technical aspects... I did hear on this forum that electrum passwords are a bit easyer to brute-force IF somebody has physical access to your PC AND you have a weak password.

You're correct about cloudmining: think about this fictive example:

I have a good electricity rate, and buy an S9... If i run my S9, i make 0.01 BTC/day profit... Why would i ever rent out my mining equipment for less than 0.01BTC/day... It just wouldn't make any sense...

So, either cloudminers try to scam you, make you pay more than you'll ever make, or sell the complete risk to you in return for a small fraction of the profits... Neither of these cases are good for you (IMHO).

I don't really agree on your advise for the OP to buy an usb mining stick, nor do i completely agree on advising him to buy an S9.
An usb mining stick will probably never ROI (i did the calculation in a previous post, just to lazy to look it up). An S9 might give the OP some profit, but ONLY if he has a good electricity rate, enough technical knowledge and an appropriate place for his S9. Additional research is defenatly needed before buying any ASIC.

My advice: stop right there, don't mine with your laptop... Period.

Years ago, people could mine bitcoins with their CPU, then people found they could reach a much higher hashrate using their GPU, making CPU mining obsolete.
A short while later, companies found a way to produce chips with the sole purpose of creating sha256 hashes, they put these chips into so-called ASIC's. An outdated ASIC is thousands of times faster than your i7, using only a fraction of the electricity, so mining with your CPU is completely obsolete.

Nowaday, you can only mine bitcoin or litecoin using an ASIC, using anything else will produce so little hashrate you would literaly have to mine for years to reach the minimal payout at a mining pool. It would literaly be more cost-efficient to claim bitcoins from faucets (making $1-$3/day in the process).

A good ASIC would be an antminer S7 or S9, but at  this point, you need one of these AND a super low electricity rate to even try to break even (plus, you need good PSU's, shelving, cooling, technical knowledge).

As far as i know, there are a couple working sollutions you could use:

• depending on the version of the wallet on your mac, you could be able to start the wallet in pruning mode... This way, 3 Gb of space is enough (i do think it takes a long time, since iirc, it needs to resync completely)
• you could export the private keys for all addresses containing coins (including change addresses), and import them into your other wallet
• Like said before, you could replace the wallet.dat on your new computer by the wallet.dat from the old one

Whatever you do, make sure you have a recent backup of your wallet.dat (both the old one, and the new one). The old one probably isn't deterministic, so an older backup might not do...

EDIT: when i finished typing, i saw 2 of my 3 sollutions were already posted while i was typing (sorry)  

Depends on a couple of factors:
- how much did you pay for those 84 S7's (including PSU's)
- what is your electricity rate
- how much do you pay for the facility (maybe electricity is already included, but also racks/shelving, cooling, security,...)

84 S7's can be profitable if the rest of the numbers are good, but you might aswell lose money if those numbers are not that good...

1) you can solo mine, i didn't want to reinvent the wheel, so i googled it for you
An example guide: http://www.titcoins.biz/faq-contact-us/titcoin-guide-how-do-you-solo-mine-titcoin/
An other option would be to start the qt wallet, open the debug console and type "setgenerate true". This feature is removed quite often, and usually has low hashrate compared to GPU mining, ASIC mining or specially compiled cpu mining software.

2) In case of GPU mining, don't forget usb power risers, don't draw the GPU's power trough your MOBO or it might burn

3) depends on your HW, you need different kinds of software to mine different algo's on different OS's using different hardware

In the future, i would advise you to only use trusted mixers... I've been around for a while, and i've never read negative comments about bitmixer.io. They also have an onion domain (bitmixer2whesjgj.onion at the moment, but you should always visit bitmixer.io to check if it's still valid).

Other things would be: double check the url, the ssl certificate AND the letter of guarantee (you can easily verify if the address used to sign the letter of guarantee is the right one, check the dates, check if your address is clearly mentioned, and check if the signature is valid before sending a single satoshi).

Like i said, these tips and tricks won't help you this time, but hopefully, it'll help you next time you want to mix any coins.

It's sad to say (at least, it is sad for you, and i do feel pitty for you), but one of the features of bitcoin is that there is no charge-back method once the transaction makes it into a block (yours was added to a block).


Creating a scam report is relatively easy: just go to this subforum:
https://bitcointalk.org/index.php?board=83.0

Follow the guide in this post:
https://bitcointalk.org/index.php?topic=260073.0

TBH, chances for you to recover your funds are slim to none, but you can always try to create a scam accusation, even if it's only to warn other people for this type of scam.

it might be a good idear to follow the proposed scam report format listed here:
https://bitcointalk.org/index.php?topic=260073.0

At the moment, nobody has any idear what the problems are, what happened, what you want cloudbet to do,... Following the correct procedure might make the process easyer.

As i feared, looking at a standard block explorer:
https://blockchain.info/tx/a5fafd809c859005e9a12fe8bc08b50db698e8aec382c7151d2bca5c0b6a6537

you can clearly see this transaction has indeed 124 confirmations at time of writing

This basically means you should doublecheck your deposit addres in the mixer's gui...
If it's really 35Ax7AcYq3WUNPHcncbRvahwYwMRk75a7h  (maybe make a screenshot), you are either scammed, or they have technical problems.

If the deposit address in the mixer's gui isn't 35Ax7AcYq3WUNPHcncbRvahwYwMRk75a7h , they either changed it scam you, or you have malware on your local pc.

Anyways... The only 2 things left for you to do are:
- if you have malware, clean your pc
- if you got scammed/technical problems with the mixer => contact their support. If it doesn't answer, at least open a scam report in order to warn everybody else...

It seems you're asking advice about the same problem in 2 different threads:
https://bitcointalk.org/index.php?topic=1637010.msg16589388#msg16589388

It might be a good idear to focus on one thread and close/post a notification in the other one, that way everybody is focussed on helping you in one place

That being said: if electrum shows allmost 100 confirmations, you either pasted the wrong address, the mixer is experiencing technical problems,  or you got scammed (at least, those are the scenario's that pop to my mind).

https://www.dash.org/x11/
Dash uses the X11 algorithm... It simply cannot be mined with an sha256 ASIC. Only sha256 coins can be mined with a sha256 ASIC.

Usually, bitcoin is one of the best things to mine with a sha256 ASIC. From time to time, other sha256 altcoins do slightly better.

Here is a calculation at current difficulty, block reward and bitcoin price. I've assumed a very cheap electricity rate of 5 cents/Kwu:
http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=23&p=7&pc=0.05&pf=1.00&d=258522748404.51500000&r=12.50000000&er=640.87000000&hc=50
The block reward will halve in less than 4 years, the diff is rising and the price fluctuates all the time.
In other words, it'll take at very least 20 years to recuperate your $50 investment, not counting the laptop price and power, nor the changes in diff, price and block reward (so in reality, you'll never recuperate your investment).

For X11 mining, you'll need a GPU, and it'll produce far less hashrate while using far more power...

If you sort this table:
http://www.mininghwcomparison.com/list/index.php?brand=both
and only look at X11, you'll see that even the best GPU's reaches only 30 Mh/s (that's 1000 times less than 30 Gh), the power consumption isn't listed, but rest assured it'll be more than the 7 Watts a geccoscience compaq uses when running

Same thing... It's an ASIC... Apart from a few exceptions like the gridseed dualminer, an ASIC is designed to only use one hashing algorithm... It's basically hardware that was designed to apply one mathematical function (in this case sha256).

This means this ASIC can only mine coins that use the sha256 algorithm (list in my previous post).

At the moment, there are ASIC's for sha256 and scrypt. If you buy an scrypt asic, you can mine scrypt coins (like litecoin, dogecoin, viacoin,...). If you buy an sha256 asic, you can mine sha256 coins. As soon as these ASIC's hit the market, it became virtually impossible to mine sha256 or scrypt coins using a GPU and a CPU because those asic's were far superior both in speed and power consumption, making it economically hard to use anything else to mine.

If you want to mine anything else (a coin not using sha256 or scrypt), you'll need a GPU for most of them (only certain specific GPU's are suitable to mine economically).
There are some, very specific, algorithms that can best be mined with a CPU, or by using a fast harddisk or a lot of memory, but a laptop cpu, HD or memory are not good enough to mine these coins either.

btw: about the gridseed dualminer, it has a chip that is designed to mine sha256 and scrypt at the same time, but it does a horrible job (both in speed and power consumption), especially for sha256. It already did a bad job when it was brand new, let alone now...

At the moment, GekkoScience Compac would be the best usbstick miner on the market today.
It should cost about 50 bucks for a 23Ghs stick.

That being said: you'll need to mine for a really, really, really long time without any power cost to recuperate those 50 bucks. If you even pay 1 or 2 cents per kwu, you'll probably never ROI (return on investment = break even).

Bottom line: USB stick miners are a learning tool nowadays, buy them to learn how to mine, but don't expect any profit from them.

If you have a good power price, you could potentially mine altcoins using a GPU, or you could invest in an antminer S7 or S9, but you need to calculate all the costs and problems before even thinking about buying one.

First off: the miner in that link is waaaay overpriced. $85 for a 5 Ghs usb mining stick is allmost a scam.
Secondly, no, you can only use this miner to mine coins that use the sha256 algorithm.

For example, the altcoins in this list could potentially be mined with that stick, if it wasn't to slow and power inefficient to actually use: http://www.coinwarz.com/miningprofitability/sha-256

Good thing you asked around on this forum first, because you would have thrown away $85 if you bought it straight away.

Fixed that for you  ... With the possible exception of giving your keys to your children or being robbed at gunpoint, you should never ever give away your private keys to anybody.

It's not really your account your accessing, in very simple terms, your private key lets you sign transactions.
If you give away your private key, somebody else can generate transactions spending your inputs, and sign these transactions using your private key.
Since those transactions would be signed using your private key, the network would conclude the transactions were valid, so miners would include them into a block, and there would be no way to recuperate these inputs.

sure I can do php, perl or bash scripts... Debugging python or ruby is a possibility to, but i can't say i'm good enough to write complex scripts in those two languages.
I've been working as a dba for a while, i'm pretty good at designing relational databases or writing and debugging complex TSQL query's.

I usually have a couple of hours to do some scripting on a daily basis, so you can hit me up if you have a job.

I'm pretty good at installing php/mysql scripts in LAMP environments.
If you really can't get it to work, you can PM me for a quote... It'll probably only costs you a couple of bucks to get this script installed.

I just looked at the trust page of the user you're refering to:
https://bitcointalk.org/index.php?action=trust;u=248430


There's a possibility his account was hacked, altough this is only an assumption, not proof...

I'll leave it to the DT members to read this topic, and maybe put a warning on this member's trustpage if they believe your scam report...
