Well, you can do most of the first step yourself: make your grandpa an account on localbitcoins, find a seller and arrange a meeting in a safe place.

He could also attempt to buy BTC using a credit card from an online vendor... Since this requires more trust in the seller, there are greater risks (in other words: there's a bigger chance you'll get scammed).

https://en.bitcoin.it/wiki/How_To_Buy_Bitcoins_With_Your_Credit_Card

Do your research before picking an online seller: some of those sites require extensive validation, some have a waiting period, some have the tendency to block accounts, some have a much higher markup than others,... read recent reviews on this forum before attempting to send a link to your grandfather.

He can go to localbitcoins and purchase bitcoins thru cash from a vendor that speaks a language he understands (if such a vendor can be found on localbitcoins).
This step should be as easy as signing up for a website, searching trough the adds, buying btc and sending a message to the seller to arrange a meetup in a public and safe place.

second step:
You install a wallet, generate an address and give this to your grandpa. He uses your address as a withdrawal address from localbitcoins.

Just some quick reply: i've PM'ed with JoenNL and i learned the following things:
- he does indeed speak dutch fluently, like the original minerjoen account owner
- minerjoen is the owner of the address that is currently in the sig of the minerjoen account (the hacker didn't change the sig)

Since the address in the sig was never posted publicly, i saved the current signature, so the hacker can't change the sig to remove all evidence (well, he can change the sig, but the old sig will be archived)
https://web.archive.org/web/20161116090930/https://bitcointalk.org/index.php?action=profile;u=337268

I hope this archived page will be enough proof for the original owner to use the address 1GPjrqoWGQfqyCEYnPhbA3nWN9dmMwFHRE to reclaim his account, altough i'm not 100% sure it'll be sufficient.

Good luck!

stiffbud is right, you'll need to create a topic in meta...
Try to sign a message with an old bitcoin address that was posted in an old, unedited topic, preferably quoted.
In this message, state the fact that your account was hacked and ask if the admin can reset the password and change the email to your email.

your options for a viable address seem limited tough... you haven't posted a lot of addy's in the past.
https://bitcointalk.org/index.php?topic=1196413.msg12555328#msg12555328
https://bitcointalk.org/index.php?topic=1062400.msg11420871#msg11420871

The only 3 addy's that could possibly be linked to your account i found so far are:
1Kh2Yuo5SLxBfCrkQuEsYNiRm7DmxfdnTM, 1HEVJiY3oHSc88sBYYmaAECbEHZfkEJrc6,18hPpuME6vTEjRY7VxfGpuqDqkTyWtTKjz


I've also found a couple of posts in the altcoin section where you posted altcoin addresses, like this one:
https://bitcointalk.org/index.php?topic=613213.msg7947517#msg7947517
But signing a message using an altcoin address usually won't be enough for theymos to give you your account back i'm afraid, but it might be enough proof for a couple of DT member to red tag your old account so at least the hacker can't use it any longer..

If you need help, you can PM me in dutch, as i've seen this is also your native language.

https://bitcointalk.org/index.php?action=profile;u=337268

Seems to exist

https://bitcointalk.org/index.php?action=trust;u=337268

It's possible it was hacked tough...

If you can no longer access your account, you might want to dig up an old quoted address, and sign a message to reclaim your account... Can't find the correct message format for password reset requests tough.

I've never used them, but a quick search didn't deliver any scam-related results:

https://cse.google.com/cse?cx=016660200577587308545%3Aesf40ml9aag&ie=UTF-8&q=tradesatoshi.com&sa=Google+search#gsc.tab=0&gsc.q=tradesatoshi.com&gsc.sort=date

Offcourse, it wouldn't be the first exchange that turned scam, ran away or had to default... So there is no guarantee tradesatoshi will ever come back.

How long have they been down?

It had been a long time since i last mined altcoins, but i had 2 spare dedicated boxes laying around and tested ZEC mining. Since we're talking about CPU mining, my servers had these CPU's:
1 x Xeon(R) CPU E3-1245 V2
1 x Xeon(R) CPU Dual L5420

The combined hashrate of 16 cores is around 30 S/s. the E3-1245 gets about 23 S/s, the L5410 around 7 S/s

The only experience i have was a small test i did depositing 0.05BTC to btcjam little over a year ago.

I made (very) small investments into 12 projects.
I allways made sure the borrower had a good rating, i liked the project and the loan wasn't suspicious (suspicious, for example, are people that have repayed 5 BTC in the past, and suddenly try to take a 50 BTC loan).

After a year, i stopped my exeriment with the following statistics:
Net return: -21%
5/12 borrowers defaulted, 1/12 is more than a month late (so in the end, i suppose 50% of the borrowers will have defaulted on their loans).

I've depostited 0.05BTC, and i've withdrawn 0.032792 (using 3 transactions, each transaction requires a fee). Substracting the fee of 0.0003681 I payed when funding my account, i can say:

I have sent 0.05 BTC to btcjam, after a year and after both deposit and withdrawal fees, i have a total return of 0.0324239. So in the end, i've lost both a year of my time and 0.0175761BTC by investing on a p2p lending platform.

That is correct. As long as a transaction is unconfirmed, it only exists in the memory of the nodes. An attacker can actually generate a transaction spending input A with a very low fee, and directly afterwards create a second transaction spending input A but with a much larger fee.
Most miners will include the transaction with the larger fee into a block, voiding the first transaction. Only waiting for at least one confirmation will protect a service against this problem.

Once a transaction is added to a block, it's allmost impossible to doublespend the inputs, but as long as the transaction is unconfirmed, it's pretty easy to do so.

My best guess is that the person who wrote the wiki meanth that once your transaction is confirmed, it's protected against double-spending.

The way i always understood the concept, double spending means only one of many transactions spending the same inputs is included in a block, the other one is cancelled. This is what makes it dangerous. You think you have received funds from somebody, but a completely different transaction spending the same input is included in a block, and your transaction is cancelled, hence, you are no longer payed.

5 BTC is enough to make some effort... I participated in the quoted topic and gave some proof of concept examples in perl on how to tackle this problem (altough, an other member wrote a much better sollution in python), in case you need some extra assistance, you're always free to PM me

0.1 Gh/s will make you about 3 dollarcent a year, while ruining your computer.

Like it has been asked before, it would be a good thing to give us the complete picture to work with

- is your electricity really free
- how much electricity can you use (it's not because it's free that you can use as much as you want... Your landlord might knock down your door, or your house might catch fire if your breakers aren't ok)
- what kind of PC do you have (let's find out if you can mine some CPU minable coins, don't expect to much tough)
- what kind of GPU is inside your PC
- do you have a budget you can spend
- which commandline were you executing when starting the OP?
- what is your technical knowledge?

Can you show us this address? Where did you see it???
Maybe it was just a note on blockchain.info or something, but with the information you gave, i have no way of knowing what happened.

quoted that for you... I'll verify the sig with electrum and edit this post when successfull.

EDIT: can't seem to verify this one, not by using electrum, not by using https://tools.bitcoin.com/verify-message/ not by http://www.coinig.com/?adr=15LxBZ12C8VW5EsDVnRG8cnzJFAEDK9EQD&msg=This+is+Crwth+from+Bitcointalk.org+today+is+November+7%2C+2016%0D%0A%0D%0AThis+is+my+address.+%0D%0A%0D%0A15LxBZ12C8VW5EsDVnRG8cnzJFAEDK9EQD%0D%0A%0D%0APlease+be+advised.+Thank+you.&sig=H8dekP3Hc6SsvT8P3dnEmCt%2Fiu2rYoTgKlWq2F5k%2BVIBKUBU5NAt%2BIFp%2FLoS59JP6%2FGbLzf2ED3i9aIMOf%2BJVrE%3D

Maybe it's because of the many linebreaks... Maybe you can try a simpler message?

It's not hard to write your own faucet from scratch, using json-rpc and running your own node.
I made a proof of concept which you can use to study how to do this, you can use the code as a basis if you wish:
https://github.com/mocacinno/simple_testnet_faucet

yes, i have the exact same problem here (Western europe)... So my guess it's a server side problem (altough it's only an educated guess)

Since i had a couple of hours today, i quickly made a proof of concept testnet faucet:
https://github.com/mocacinno/simple_testnet_faucet

It's a PROOF OF CONCEPT TESTNET FAUCET, DO NOT RUN IT ON THE MAIN NET!!!!! It will work, but your funds will be drained in mere days
I did nothing, repeat nothing, to avoid abuse of this system, nor did i check for security vulnerabiltys...

If you want to use this faucet as a mainnet faucet, you'll have to extend/fix/patch this code and at least:
- check for possible vulnerabilitys
- add ref system (add a table, insert each address as a user, keep track of the referring user, when running cronjob.php insert record in the faucet table to pay out refferer)
- kick bots
- kick proxy's
- kick VPN's
- kick tor
- create blacklist
- create admin page
- add extra checks: 1 claim per ip, 1 claim per address,...
- add captcha
- make a nice gui
- add an installation script
- add bitcoin.conf sample
- implement session
- implement ad management
- test the hell out of it
- ...

I'd probably just install bitcoin core, and run a daemon in testnet mode... Then i would create a php/mysql script to use json-rpc in order to generate transactions when a claim was made. Especially when talking about testnet, it's all pretty basic stuff. Just a form an a captcha. When info is posted, enter the ip and timestamp into the db and check if a claim can be made. If true, either make a json-rpc call, or store the info into a db and run a cronjob to query the db and make the transaction on an hourly/daily basis)

You could probably use an open source script like this one to do the same thing:
https://github.com/tuaris/FaucetRPC

(disclaimer: just found this script by searching github, i have no idear if this one is secure).

EDIT: if it's 100% sure testnet only, i'd be willing to invest a couple of hours in order to write something up whenever i have some time (might take a couple of weeks tough)

Please, read this tagged post, written by a trusted member and adjust your OP accordingly:

Next to this, 0.01 is allmost 7 bucks nowadays (this is not a little number, considering there are a couple dozen accounts created each and every week with the sole purpose of asking for no-collateral loans), and taking loans for the sole purpose of building trust is heavily frowned upon by the community.

If you're 100% sure your strategy works, go to a bank, take a mortgage of $100.000 on your house.
1,5% compounded daily will make 22.575.604 in one year. Banks in my country have a yearly intrest rate of about 3% at the moment, so you'll need to pay back ~103k-105k, and keep more than 22 million.

I can honestly say i don't really trust people that say they have a money making idear, but instead of using it themselfs, they publish it in an ebook... Always smells fishy to me.
