Hello,

I would like to know if Ian Coleman mnemonic is still updated and safe to generate BTC address and key.

Also, are there alternative to this browser based solution?

My main goal is to generate BTC address on my own with javascript on a browser only without being connected tto the internet?

Thanks for your help

Hello,

I have already had this discussion however I still have trouble understanding how can't someone with good computer can't get a private key of a BTC address with BTC on it and just withdraw the BTC.

Even if I have BTC on cold storage, what if someone get my private key by accident just by generating a new address on its own wallet.

this only a question of probabilities. Can you prove this will never happen?


thanks

Hello,

I have used for 1 year the ian coleman Mnemonic Code Converter (https://iancoleman.io/bip39/) to manage my BTC

However I would like to generate  Bech32 address for efficiency with my wallet (thanks to words mnemonic).

Is there a way to do so with ian coleman Mnemonic Code Converter or other ?

Is it safe to keep BTC on P2PKH address?

thanks

Hello,

I am looking for the equivalent of coinb.in that is for btc BUT i need  this for monero.

coinb.in is browser based tool that allows to sign(offline), verify(offline) and broadcast (online) btc transaction.

I just want to do the same with monero. Hasn't it been invented yet?

thanks.

Hello,

I usually get this question of people wanting to anonymize their BTC.

To this, the answer is one of the 2 methods :

1) use BTC mixer such as WASABI
But there are talks about people getting involved in illegal things just because their BTC were mixed with illegal related BTC.

2) send your BTC to an exchange like bitbox, kucoin, huobi ... then buy monero, send them to another exchange like  bitbox, kucoin, huobi ... and buy back BTC
But what if those exchange are linked together so that monero transaction between two of them will be identified.

Are there other methods? what is the best method between the two above?

Thanks

 

Hello,

I would like to create my own hierarchical deterministic wallet like a paper wallet. Mainly because I want a new address for every transaction and I want to be totally in control of the wallet (so no hard ware wallet or app wallet)

Here are my questions :

1)For example, I have used https://coinb.in/#newHDaddress. Are there other places to do this?


2) on https://coinb.in/#newHDaddress :
By clicking GENERATE I get

xPub Address :

xpub661MyMwAqRbcGUuv17GHY2HyJYV73nTpvTandSM1sfGwMoLwt4vyPyvTUHfmpC31KypDxhRa5D3 QMFbnGkWVvGNz3Y9eoGwzj91r1QmpDi1

xPrv Address :

xprv9s21ZrQH143K3zqSu5jHAtMEkWeceKjyZEfBq3wQKKjxV11oLXcirBbyd2QZCyPjxbdYQtQGP6E JR3iXuZNBiSw8jaBRs6NdWF1kTSnMJCV

Is it this really done randomly like in  https://www.bitaddress.org/ with no risk of being bruteforced or compromized?

2) in below  "Address Options", "Custom Seed or Brain Wallet", I can type whatever I want? what is the use-case for this field?


I have other questions but let's first answer those above.

Thanks,

fred

Hello,

I found out that maybe one day, it will be able to find private key from a public key using quantum computing (around 2030)

1) it is said that using several time the same BTC address is risky. I am using a paper wallet with a unique address. How can I use another address with the BTC arriving on the same paper wallet?

2) I have heard that quantum computing will be able to acted for craking a public address ONLY during the transaction process? is it true or not?

3) except making the public address more heavy, what are the options for BTC to be saved from quantum computing?

Thanks for your help.

Hello,

We could see the coming of new altcoins in the last few months and years.

They are mostly non-minable, backed by a company or backed by fake non-profit foundation, their founders made sure to be loaded with coins before launch.

Those altcoins claim to be decentralized and more efficient than Bitcoins and historic coins.

However, most nodes are run by the organization behind the altcoin, the change in algorithms are made by this organization even if the code is open source,

they claim little to zero fee transaction and instant transaction but these are just words : what would happen really as the network get congested like bitcoin?

They show road map about what the coin will be (zero fees, instant transaction) but we have no proof of this as it is still not real

Those coins are clearly to much branded, they are just paypal.

Indeed, I am talking about : Ripple, Cardano, NEO, NEM, NANO and others


Thanks

Hello,

I am in a situation where I own BTC on the same address as BCH and I would like to exchange BCH for BTC.

1) My plan is to move my BTC to another address before moving my BCH to exchange service. am I right to do so?
2) I don't know if I can move my BTC to another address as some people say the Bitcoin gold hard fork has already taken place. So I assume there is a risk to loose my Bitcoin gold doing this?
3) is there a script like coinb.in to create and broadcast BCH transaction?
4) is there a risk loosing my Bitcoin Gold by moving my BTC or my BCH right now as some says Bitcoin Gold hard Fork has already taken place?

Thanks for your help,

Hello,

I would like to exchange BCC for BTC with anonymity.
Somebody suggested Bittrex.com but they require address, name DOB.
 Where can I do this?

thanks

Hello,

I have performed a transaction by myself using coinb.in for a small amount of BTC. After broadcasting it, coinb.in gave me a transaction id.

However, after several hours, the recieving address hasn't been credited yet, the sending address hasn't been withdrawn and when searching in blockchain explorer for the transaction id nothing is found?

I have put a small fee, but this should only impact the confirmation, the transaction should still be displayed on the network. So why am I not seeing it?

Hello,

I want to make a transaction from my BTC paper wallet to another BTC paper wallet that I own.

What is the best way to do that? (I don't want to retrieve my paper wallet through blockchain.info or else, I want to make transaction directly to my other paper wallet)

Thanks for your help.

Hi,

Up to now, Bitcoin hasn't gone through financial crisis. Maybe one financial crisis is near (look at financial market overvaluation)

in case of financial crisis, bitcoin price could
-collapse as big money people will withdraw from any investment,
-surge as BTC could be seen as an escape to current financial system
-remain stable

Do you think that in case of a major financial crisis like in 2008, bitcoin price will collapse, surge or remain stable?

thanks

Hi,

I heard that in order to use segwit one has to create a BTC segwit address and to make segwit transaction.

Since the Hard fork of beginning of august 2017, I haven't move my BTC from my paper wallet. So my BTC (and BCH) are on an old BTC address.

Can someone confirm there is no issue leaving my fund on this wallet even with segwit now activated?

thanks

Hi,

currently there are on average 300 000 BTC transaction per day.

My question is : is it possible to keep 1 mb block (with technical solutions) while the transaction numbers per day increases to 1 million, 10 millions, 100 millions...?


I think that LIGHTNING NETWORK can make this possible because for every transaction channel where can happen unlimited transaction there is only one transaction happening on the BLOCKCHAIN. why some are skeptical about Lightning network?


People defending segwit2x don't understand how lightning network would work and can work with 1 mb block size with unlimited transaction per day.

People defending segwit2x and block size increasing, see it as the only way to lower fees and to scale BTC.

To those who are saying lightning network is bad :
1) Some people think that LN only lower fees for those who are doing a lot of transactions. If you stay in the lightning network a very long time, you will be able to do little transactions per unit of time and only paying once onchain transaction fee to get to the lightning network and once to get out. You will also pay for using lightning network every time you do a transaction but very little.
Even if Alice is doing one TX per month, If she stays 1 year in the channel, then, she will pay only once onchain transaction fee to get to the network and half onchain transaction fee (split between the two channel users) to get out.
2) some people think that you have to create a channel for every user you send money to. But no, you have to create only 1 channel with another user. Then you will be connected to the network and your transaction will find its way through the network to the user you want to pay. Your wallet finds a route through the network to those people as explain here
https://bitcoin.stackexchange.com/questions/43700/how-does-the-lightning-network-work-in-simple-terms
3) LN will lead to centralization. why? If a LN is too centralized and make decision that make its user unhappy, then its users vote with their feet and leave the network, close their channel. They create a new network on their own. No big central entity will be capable of controlling this. Meanwhile, the blockchain remains with small size blocks enabling plenty of nodes that keep the system decentralized.

The way I see it is : Blockchain : the place where you store your value
                            LN : the place where you use your value to pay for things   

Our mission is to explain them how lightning network works for the sake of BTC in the long term because they just don't understand lightning network. This is just a question of communication but this can make BTC to the moon.



thanks

Hi,

I would like to know if only miners can fork the BTC blockchain by themselves or if they need to have user support to do so.

Because miners and users don't have the same interrest regarding bitcoin.

thanks

Hello,

As it is called UAHF (User activated Hard Fork), this change in software is made by users.

the change will affect blocksize to 8 mb. However, increase in blocksize will lead to more centralized network, which is something user don't want.


So users are deciding to make a change that they don't want. Not very logical. So what?

thanks

Hi,

Hello,

I am wondering how people seeing a great future in BTC can imagine huge increase in the number of transaction per unit of time without increasing block size.

thanks

Hello,

I have created a paper wallet. I have a encrypted private key with password and a bitcoin public address.

using bitaddress.org, Ihave tried to decrypt the private key with password (doing this offline) and this worked fine : I recover the BTC address and the private key with no encryption...

However, I am wondering if this is enough to make sure that my private key is valid?

thanks
