Looks like that person might be trying to scam you... Like TheGoodMiner said: there's no way that hashrate can be true... There isn't a bios setting you can use to do this.

I don't know if they use BTC, don't care either... I do know that some of their supporters are active on this forum:

I gave him a neutral tag a long time ago...

that code also looks like C++

This one?

I bought some LTC during the last drop... Hope it'll go up again shortly... 

A couple of questions:
1) are these hacked, or legit accounts
2) do you accept escrow
3) any vouches?

AFAIK, everything can be used to bribe somebody... This includes bitcoin.
At least, in my country, a bribe is not defined as money, it can be a nice holliday, a new pair of shoes, a dinner, cash,... So why wouldn't bitcoin be considered as a bribe.

Hope is 99% lost, but like DannyHamilton already said: it's always worth a shot to at least contact BraveBunny's support.
If they don't respond, you would do the community a favor by posting proof that you were scammed either in their support thread, or in the scam accusation subforum (read the stickies first tough).
This way, you can at least help other people, so they don't fall for the same scam as you did.

Using google, i found this link (second hit for searchterm "sign message blockchain.info"):

https://forum.bitcoin.com/technical-support/how-to-sign-verify-message-in-new-blockchain-wallet-t9736.html

I agree with everything pooya87 said, i only wanted to add that, since you're in the alternative clients subforum, i do think some of the alternative clients actually ARE pretty newbie friendly.

I personally suggested multibit HD to a couple of new users in the past, since i personally think it hides a lot of the complexity... Offcourse, once a new users starts to learn about bitcoin, multibit HD might be a problem since it misses some coin controll features that are needed by more experienced users (like input selection, fee manipulation, exporting private keys,...).

In the end, it seems like a tradeoff, either you pick a wallet with a full feature set like core, but end up with a wallet that is not so newbie friendly.... OR you pick a wallet that's newbie friendly but might be missing some more expert functions.

If you're from europe: the ALDI market (i suppose they're in most of europe) has these meters about once a year, they cost like 7€ (IIRC).

Do you mean you've sent to much BTC, or do you mean you think the service was overpriced?

If you've sent to much BTC => As soon as a transaction is confirmed, it's (allmost) impossible to "charge back", as soon as it has a couple confirmations, it's certainly completely impossible.
The only thing you can do is hope that the vendor refunds you, and maybe open a thread in the reputation section or scam accusation section if he refuses to do this.

If you think the service was overpriced, there's nothing you can do either i'm afraid

Normally, legit posts aren't deleted. MOD's usually only remove spam or double posts... What you can do is lock this topic (left bottom corner), that way it can't be posted in anymore.

Looks like a neat tool, tried it on some of my own domains but the data didn't seem to match...
My domains are behind cloudflare tough, so that might be the issue?

Haven't received any mail from the OP... I'm closing the disposable email addres for now...

Personally, i see a couple of red flags when a newbie offers a luxury watch at discount prices without mentioning the price, doesn't mention escrow, doesn't know how to post images on imgur, doesn't send the pictures to a public email address,...

I'm not saying this is a scam (i have no proof for this), i'm only saying i won't use OP's service myself, because it feels a bit fishy...

I've created a temporary email: cejuhibod@cartelera.org
If you send me valid pictures within 15 minutes, i'll post them on this thread...

A valid picture is: a clear picture of the product, with your hand holding a piece of paper stating your forum name and todays date...
If the picture is obviously photoshopped, not clear or does not include your hand holding a piece of paper with written data + forum name, it's not valid, and i won't make the effort of posting it.

Also i find it weird that you cannot use imgur... Makes me wonder if you'll be able to figure out how escrow works...

2 options:

open your wallet, go to the debugconsole and do "setgenerate true" (might not work for all wallets/coins). Some wallets have the mining-option built-in in their gui to make it easyer for you

or
open your .conf-file, edit it more or less like this (example for litecoin)

run your wallet
download a mining program, depending on wether you'll cpu mine (bad idear), GPU mine (still not that good of an idear) or if you'll mine using an ASIC. Run the program with the parameters you've entered in your .conf

Just to be completely honest, you'll probably make a lot more coins if you just sell the laptop for BTC or sell it for FIAT and buy BTC with the proceeds
Offcourse, if it's the learning experience you're after, XMG used to be pretty stable (don't know if it's still true today, i stopped mining it a couple months ago)

I used to mine XMG (magicoin) on a spare server that i already payed hosting for. Made a couple of bucks, but i didn't ROI on the rent tough . That being said: you do have something to lose... CPU mining on a laptop will probably kill your laptop.
