Re: I'm Eric Larchevêque, Co-Founder and CEO of Ledger, makers of hardware wallets, Ask Me Anything!

This is not really a question, but it relates to your business model.

I want to hold a considerable amount of bitcoins, and I'm looking for a very resilient and attack-proof solution. The problem with the current solutions in the Bitcoin space is that these small devices:

1. Connect to my computer ...

Re: I'm Andreas M. Antonopoulos, author of "Mastering Bitcoin", public speaker, podcaster and pundit. Ask Me Almost Anyt

I never really got bitcoin until I read your book. After that, I become interested in the technology and bought a good 5 figures (USD) of bitcoins. I think most of the negativity that comes with it, is due to ignorance.

1. Do you really think that Bitcoin has over 1million active users? It seems to ...

Re: My Setup for Cold Storage. Looking for advice.


6. Using my connected laptop, I retrieve the Transaction id and Script of the transaction that I made. I write those down on paper. I then go to my air-gapped machine and I enter these information to create the transaction and sign it.


I wonder, why you are not also using QR for this. If you ...

Re: My Setup for Cold Storage. Looking for advice.



I've been thinking about that too. I'm waiting for my Trezor and looking to buy the KeepKey if I find a way to ship it home. That being said, they'll be used for active transactions.

The cold storage will be used as a single point for storing bitcoins for the very long term.

I have a question ...

I'm curious to know the volume of BTCs Bitpay is handling. Is this something you are willing to share?

Re: My Setup for Cold Storage. Looking for advice.

Multisig is more secure in that in requires more than one private key to access the funds. I suppose some people are paranoid of a collision from poor RNG and someone else will get access to their private key(s)?

Multisignature is more secure than one signature until you make your first ...

Re: My Setup for Cold Storage. Looking for advice.

Can any one explain why the multisig is more secure than the usual one sig?

I can understand the power of multisig when you have one/two private keys stored in alternative services/sites/places. But if you are using a single place, how does multisig help?

I have already looked into Bitgo, coinbase ...

Re: My Setup for Cold Storage. Looking for advice.

that is a pretty sophisticated plan dude. iam no security expert but i would say that should be good.

is it a very large amount that you want to store?

i always recommend to people to use 3-4 methods of storing for their coins. maybe (maybe) there is a bug in your big plan, then the other 2-3 ...

My Setup for Cold Storage. Looking for advice.

I'm planning to store some bitcoins in cold storage. I'm doing a very simple setup, no complicated algorithms, no wallets...

Here is my plan

1. Create an air-gapped machine with a Linux distro. The machine won't have access to Internet and I'll disable wifi/mobile connection on purpose to be sure ...

Re: Should I opensource bitcoin payment gateway?

The forum will benefit from better moderation.

Otherwise, the real question is: Why Should you NOT publish it?

Is it because you are fearing it'll lose people money? Then maybe you should make them more careful.

If you think it is because it's worth more than 0$ per clone, then you answered your ...

Re: I am Wences Casares, co-founder & CEO of Xapo, Ask Me Anything



2. Xapo only uses muti-sig technology. When you are using our wallet or our vault you are using multiple signatures that are kept in different locations, etc. If you want to spread the risk in multiple people you can add users to your wallet or vault with different permissions for each, but the ...

Re: I am Wences Casares, co-founder & CEO of Xapo, Ask Me Anything

Hi,

1. If you have a vault service, does that mean that the funds at my wallet are insecure? If the security level is the same, why not just have delayed withdrawals for large amounts?

2. Is there something in Xapo like Coinbase "multisig" wallet?

3. Will you freeze my funds if the gov. ask you ...
