If you accidently send your mnemonic code instead of your address to your friend, then just transfer the Bitcoin to another wallet immediately. Simple

Thank you, I've received the vouch.
The vouch account will be expired in 8 days, and the country can't be change.

As I know, the Campaign Manger (Gianluca95) is banned from the forum because of spamming [CMIIW].

Bumping, but not replying the questions??

I was just thinking to installing a Bitcoin Core on my computer, because I've never really done it before. The problem is, this is an old computer. And sometimes is often freeze (The screen still on, but can't do anything), the only thing I can do is just forcing it to off by press & holding the power button.
Now the question is, is it actually safe to use a Bitcoin Core on my computer? considering that my computer can got freeze suddenly.

At first, I think you're telling the truth. But after reading about the "bird fountain", I suddenly smelled a lie.

Can I have a vouch?

Never heard of them before, BitPay sounds nice by the way. But sadly, it's not available in my country.
And indeed lately, more and more companies are making their own Bitcoin Debit/Prepaid Card.

China is just being to hype for Bitcoin, especially for the halving. This is could be a good thing, and also bad thing if the amount keep increasing.

Did you buy this account? If you're a Senior Member, than you must already have a plan to earn your Bitcoin. Cos you already a Sr. Member which takes quite a long time to be here watching how Bitcoin grows.

That's true, it will drop the price. We won't even care about it anymore, maybe we would make a new Bitcoin with an improved security system.

Of course I have it, what's actually wrong with it? Are you not allowed to have an Android phone when you already have an iPhone? or are you not allowed to buy a new car when you already have a car? It doesn't make sense.

Why bother to sell the Bitcoin when you can actually use the Bitcoin for your vacation without selling it first.

What a pretty smart scammer, how could they use that address "noreply@blockchain.info".
By the way, why'd you cover that bitcoin address?

The answer is simple. If you lost your phone, than you're done.
But if you could erased the data of your phone (by any method) before someone's using it it, than you're pretty safe.

A Bitcoin bank? I think that won't be possible. Even tho if any bank would do that, I'm pretty sure there will only a few people that'll interested by it.

No it's not, there's are still many service that also be able to do that. You can use Wirex or advcash that actually do the same thing as it is.

Because you're still a student, you should just do what you should do (study). You can use your spare time to earn Bitcoin on the net, but you also have to focus yourself on your study. Because it's an important thing for your life, like the parents usually say .

Aman gak sih gan kalo ikut gituan? soalnya sebelumnya saya belum pernah ikut lotre kayak gitu

If they want to do it, they have to control all of the network on the internet. Or they can do it with the other way, by owning >50% of all the Bitcoin which likely not possible.
