1  Alternate cryptocurrencies / Altcoin Discussion / Claiming Airdrop coins using Ethereum on: April 24, 2018, 10:17:33 AM
Hi All,

I have my JSON file corresponding to ETH wallet however I have not opened this wallet for more than 2 years now. I wanted to know the following:

1. The best possible wallet to use to access the ETH coins from the JSON file? Is MyEtherWallet still a good choice? Per my understanding, they would need my private key to be able to access the coins. So, does it mean MyEtherWallet will store my private key?

2. There have been several hard forks in the past 2 years related to ETH and ETC. Can I still claim those coins using MyEtherWallet?

3. How can I access those airdrop coins? I understand that several blockchain projects have decided to airdrop coins to ETH holders. So, how can I get access to them?

Thanks.
2  Alternate cryptocurrencies / Altcoin Discussion / How to get Bitcoin Gold for Bitcoin Core Wallet Users? on: November 24, 2017, 09:52:16 AM
Hi,

I use Bitcoin Core Wallet. I have my BTC stored in that wallet and I own the private keys as well. How can I get the corresponding Bitcoin Gold now?

Per my understanding, at present, only few hardware wallets like Ledger, Trezor and few software wallets like freewallet have this support. However, I think the coins were supposed to be stored in these wallets at the time of the Bitcoin hardfork to get the corresponding BTG coins.

Is there any option available for Bitcoin Core Wallet users to get the BTG?

Thanks.
3  Bitcoin / Bitcoin Discussion / Did you ever convince or encourage someone to invest in Bitcoin? on: November 01, 2017, 04:00:41 PM
Bitcoin has been awesome and will always be awesome. We, who have been involved in Bitcoin since the very early days understand this very well. However, for the laymen, for the people who don't really understand the technical aspects of Bitcoin or those who only watch the mainstream media are skeptic about Bitcoin. Since, all they hear in the News is how Bitcoin can be used for illegal activities and how it offers complete anonymity (common misconception) to people to do what they need on Internet.

Have you ever convinced or encouraged anyone to invest in Bitcoin and did you have success? Of course, since we know that we are giving a good advice, so we would usually advice our own family members or friends about this.

In the past few months, I encouraged some of my friends to invest in Bitcoin. They had a lot of questions about it from technical perspective and I helped them understand. They invested in Bitcoin and are very happy with the returns. And now this information propagates and more people will get involved in Bitcoin.

In my humble opinion, as a Bitcoin enthusiast, we can help understand people the positive aspects of Bitcoin. The price of Bitcoin is still in the very initial stages and those of us who really understand what Bitcoin offers, know that Bitcoin Price is only 1/10th of what it's worth right now.

What are the most common responses you get from laymen about investing in Bitcoin?

Some popular ones I receive are:

1. "Oh, it's already too expensive, I cannot afford to buy it."
2. "The governments don't regulate it, why should I invest in it?"
3. "It's an illegal currency and only cyber criminals use it."
4. "What backs up Bitcoin? For example US Dollar is backed by Trust (all time favorite response Cheesy), but what backs up Bitcoin?"
5. "The market is way too volatile to invest."
6. "You can't really use Bitcoin as a currency."
4  Bitcoin / Bitcoin Discussion / Bitcoin Mining Profitability on: October 31, 2017, 11:32:42 AM
The site, fork.lol allows us to see the Bitcoin Mining Profitability based on fees, exchange price and mining difficulty and compare it with Bitcoin Cash mining profitability.

I wanted to know how exactly is this value calculated? What are the implications of it on the price of the coin?

So, if BCH is more profitable to mine then the overall Network Hash Rate in BCH will increase as more miners would switch from BTC to BCH mining. And with the increase in Network Hash rate, this would result in increasing the mining difficulty.

I want to understand how we can relate the Mining Profitability of BTC and BCH to the price of the coin.

Thanks.
5  Alternate cryptocurrencies / Altcoin Discussion / Best wallet for Ethereum on: October 15, 2017, 06:21:36 AM
Hi All,

I setup my Ethereum wallet long ago, sometime in early 2016 if I remember correct. I saved my wallet in a safe place and since then I haven't used it.

Now, Ethereum has undergone several developments, 1 hard fork (Ethereum Classic) and so on. I would like to know which wallet should I use? Are the latest versions of the wallet compatible with previous versions? Can I import my old wallet file into a new one? I think the format of the wallet was in JSON before. Please let me know. Thanks.

6  Alternate cryptocurrencies / Speculation (Altcoins) / Future of Bitcoin Cash? on: August 29, 2017, 09:22:02 AM
Hi All,

So, Bitcoin Cash price has fallen down after going as high as 1000 USD. What do you think is the future of Bitcoin Cash?

The Segwit activation in the Bitcoin Network went through successfully. I am not sure about the actual improvements in the Bitcoin Network with respect to Number of Transactions/second or the Transaction Fee after Segwit activation however do you think Bitcoin Cash is here to stay with its 8 MB block size?

Also, there are speculations that Bitcoin Cash might be centralized and most of the mining power is controlled by only few nodes.

And I read that miners are switching back and forth between Bitcoin and Bitcoin Cash since in some cases the Bitcoin Cash network difficulty is lower and more profitable to mine.

What are some of the major events in the pipeline for Bitcoin Cash?
7  Bitcoin / Development & Technical Discussion / What exactly happens during Blockchain Synchronization? on: August 28, 2017, 06:14:17 AM
Hi All,

I am trying to get back into the technical aspects of Bitcoin. I was quite active several years ago however now I would like to understand the ins and outs of Bitcoin and Blockchain technology much better. Also, trying to refresh my knowledge.

So, when we start the Bitcoin Core client (full node), it tries to download the Blocks. I saw it mentioned in several places that the speed at which you synchronize depends not only on your Internet connection speed but also on your Processor speed. I would like to understand what role does the processor speed play here?

Besides downloading the blocks, is the full node client also performing a Digital Signature verification for each transaction included in that block?

Also, I noticed that the newer blocks in the blockchain take longer time to synchronize than the older blocks. Is it because the newer blocks include more number of transactions and so the full node client needs to perform more number of verification per block?

Is there any way to speed up the process of synchronizing the blockchain? Of course, besides buying the latest and fastest processor Cheesy

Thanks.
8  Alternate cryptocurrencies / Altcoin Discussion / Reusing Bitcoin Core Blockchain with Bitcoin Cash wallet on: August 28, 2017, 06:08:41 AM
Hi All,

I need some help. I am trying to import my wallet from Bitcoin Core to Bitcoin ABC wallet to get my BCC. I have already moved my Bitcoins from the original wallet of Bitcoin Core to a new instance of wallet in Bitcoin Core. Now, I need to import my original wallet into Bitcoin ABC wallet to get my BCC.

Now, the issue is that Bitcoin ABC wallet is taking very long to synchronize the blockchain. It's been almost 1 week since it's running and till now only blocks till May 2016 have been synced. I still need to wait around 2 to 3 weeks more for the sychronization process to complete.

So, I need an alternative solution now. I already have the completely synced blockchain for Bitcoin Core. I know that both the blockchains are not entirely same. The pre hard fork blockchain history is the same (prior to August 1st) however after August 1st the Bitcoin Core blockchain is not compatible with Bitcoin ABC wallet.

Is there any way I can re-use the Bitcoin Core blockchain with Bitcoin ABC wallet so that Bitcoin ABC wallet recognizes the incompatible blocks, discards them and then starts synchronizing again from August 1st? It would save me a lot of time.

Please suggest some alternatives. I don't think Bitcoin ABC wallet full sync is an option for me right now since it's taking very long.

Thanks.
9  Alternate cryptocurrencies / Altcoin Discussion / Using Bitcoin Core Blockchain with Bitcoin Cash on: August 27, 2017, 10:48:12 AM
Hi,

I have a question. I am using Bitcoin Core wallet for Bitcoin and Bitcoin ABC wallet for Bitcoin Cash.

I have the Bitcoin Core wallet synced completely. Now, I would like to re-use the downloaded blockchain of Bitcoin Core with Bitcoin ABC wallet. However, the issue is that after August 1st, the blockchains are not compatible with each other.

Is there an option where I can re-use the completely synced Bitcoin Core blockchain with Bitcoin ABC wallet? Maybe, there is a way that Bitcoin ABC wallet will validate the blockchain and start syncing and downloading blocks after August 1st?

Thanks.
10  Alternate cryptocurrencies / Altcoin Discussion / How to get BCH from my existing Bitcoins? on: August 20, 2017, 06:49:46 AM
Hi All,

On August 1st, the Blockchain splitting occurred. I know that some Bitcoin exchangers automatically credited the accounts of users with equal number of Bitcoin Cash coins (BCH) as they had Bitcoin.

However, I wanted to know that if I have some Bitcoins on my local computer. I have the complete wallet and I own my private keys. In that case, can I do something now to get those BCH as well?

I am using Bitcoin Core version: 0.13.1.0 and the last time I opened my wallet was before the Blockchain splitting occurred.

Thanks.
11  Bitcoin / Bitcoin Technical Support / Using old version of Bitcoin Wallet after Fork on: August 20, 2017, 06:46:33 AM
Hi All,

I am using Bitcoin Core version: 0.13.1.0 - Bitcoin Core (GUI node for Bitcoin). I was using it successfully prior to August 1st. While I was on vacation in August, the hard fork happened and blockchain splitting occurred.

I haven't opened my wallet since the fork happened and I wanted to know if there will be any issues if I open this version of Bitcoin Core Wallet now? Will the coins be safe?

Thanks.
12  Bitcoin / Bitcoin Technical Support / Unconfirmed Transactions on: December 14, 2015, 06:24:44 PM
My bitcoin transactions are unconfirmed since 11th December 2015.

Below are the 3 transactions:

Transaction #1 of 0.134 BTC: https://blockchain.info/tx/c66637778efae6faa30e679c9f18e3b1e3fc9ae70f6e2d3fe09755af22ba63b8
Transaction #2 of 0.1777 BTC: https://blockchain.info/tx/9da82bb9d28b02f39166c774b213dec5529e11c4509c00d7dd31f075368b6b52
Transcation #3 of 0.1843 BTC: https://blockchain.info/tx/eb29b90074d024c13d4feee0991c3220b48305536895019fe830de74a5dda24a

I understand the transaction #2 and #3 will be confirmed only when Transaction #1 will be completed. Also, transaction #2 and #3 show as double spend on blockchain.info. I think this is because transaction #1 has not yet completed and transaction #2 and #3 are using the change left from transaction #1?

Also, in my Bitcoin Wallet's Transaction history, I can see that they are made at the following timestamps:

Transaction #1: 11th December 2015 - 02:57
Transaction #2: 12th December 2015 - 00:43
Transaction #3: 12th December 2015 - 00:43

It has been 3 days since Transaction #1 and it is still not confirmed. Could someone please help in understanding what is the issue here?

My last successful bitcoin transaction was on 9th December 2015 and it went through successfully. It has 1008 confirmations.

How long would it take for my transactions to be confirmed?

Thanks.

14  Bitcoin / Bitcoin Discussion / CCBill IPSP and Bitcoin on: May 26, 2014, 09:29:45 AM
Recently, an IPSP (Internet Payment Service Provider), Verotel added an option for Bitcoin Payment. A lot of online merchants (50,000 per the info on Verotel site) use Verotel, this should help making bitcoin more popular.

Would be great if after a while Verotel release some kind of statistics about how many purchases were made  using Bitcoin and so on.

CCBill however still seems to be a bit reluctant to adopt Bitcoin. Here is an article which explains some of the concerns for CCBill regarding Bitcoin:

http://www.ynot.com/content/119628-bitcoin%92s-time-yet-come.html

I think, now that we have Verotel accepting Bitcoin, its time for CCBill to join the crypto currency world as well Cheesy

What do you guys think? Will we see more payment providers (especially for adult industry) like CCBill, Epoch, Segpay start accepting BTC as well?

I am not sure if there was any presentation or talk related to Bitcoin this year at Xbiz Summit. But last year, we did have a presentation by Tony (from Bitpay) at Xbiz Summit for BTC.
15  Economy / Digital goods / Buying Virtual Prepaid Credit Card with Bitcoins on: April 23, 2014, 04:51:42 PM
Hi,

I want to buy a Virtual prepaid credit card using Bitcoins. I know that there are several such services out there. I have a few questions:

1. Which are the most trusted ones?
2. Do they send you a physical prepaid credit card shipped to your address or do they give a virtual credit card (with important details like CC number, CVV code, Validity Date and other information necessary to use it online for purchases)?
3. I want to use this card for purchasing membership to certain sites which accept payment through payment gateways like CCBill, Verotel, Inet-Cash and so on. Will these prepaid cards work there as well? Those Payment gateways ask for other personal information like First Name/Last Name, full address and email address as well.

Please note that I am looking for a Virtual Prepaid Card which is loaded with a specific balance and I want to use it only online for purchasing memberships.

Thanks.
16  Economy / Services / Buying Site Memberships on: March 29, 2014, 11:35:50 AM
I want to buy memberships to certain sites. However, these sites only accept payment through Credit Card or PayPal. I cannot make the payment through either of these myself.

I have bitcoins but these sites do not accept bitcoins. So, I am looking for someone who would help me buy memberships to the sites I want and in return I will give them BTC (at current market price equivalent of the membership of site) and in addition to this an extra incentive.

for instance, if the 1 year subscription = 100 USD

so, BTC equivalent = 0.2 BTC according to current price of BTC.

The advantage for you is, the price of BTC might increase with time, so it would be more valuable for you than the initial 100 USD you paid for me through Credit Card/PayPal.

Also, I will pay slightly extra BTC for you since you are helping me out. If you think you are interested in this kind of deal, please post here or contact me through PM on the Forum.

Thanks.

19  Bitcoin / Development & Technical Discussion / How exactly do Transactions work in Bitcoin Network? on: March 08, 2013, 07:09:23 AM
I was reading about Transactions on the wiki here:

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

From what I have understood, a Transaction will have inputs and outputs. Inputs will reference the output of some other transaction. At the same time, output will have the details of sending bitcoins.

How does this relate to a simple example in Bitcoin Network such as:

"at this very moment, when all the nodes in the Bitcoin Network are working to complete a new block, let's say, Bruce sends 1 BTC to Linda's Bitcoin Address".

What exactly happens now?

How will the Bitcoin Transaction format look like? What will be the inputs and outputs?

I am trying to correlate it to what is mentioned on the Wiki about Transactions.

Will this information (Bruce sent 1 BTC to Linda), be announced to all the nodes in the Bitcoin Network?
How exactly do other nodes in the Network verify this Transaction?

example from wiki:

Code:
Input:
Previous tx: f5d8ee39a430901c91a5917b9f2dc19d6d1a0e9cea205b009ca73dd04470b9a6
Index: 0
scriptSig: 304502206e21798a42fae0e854281abd38bacd1aeed3ee3738d9e1446618c4571d10
90db022100e2ac980643b0b82c0e88ffdfec6b64e3e6ba35e7ba5fdd7d5d6cc8d25c6b241501

Output:
Value: 5000000000
scriptPubKey: OP_DUP OP_HASH160 404371705fa9bd789a2fcd52d2c580b65d35549d
OP_EQUALVERIFY OP_CHECKSIG

If someone can correlate it, it would be great.
20  Other / Beginners & Help / Need an Alternative for Tradehill! on: February 05, 2012, 04:46:36 AM
Hi,

I have been using Tradehill as the bitcoin exchange so far. All the bitcoins I used to mine were automatically transferred to Tradehill Account.

After I collected a good amount of bitcoins, I decided to convert them to my currency and cash them out by withdrawing to my local bank account.

I requested for the withdrawal on 2nd Jan 2012, and it has been pending since then.

I contacted their Customer Support Service and all they did was provided me a complain ticket number and asked me to follow up using this number as a reference. I have tried contacting them, but no luck! It sucks and Tradehill is the reason I stopped mining bitcoins for almost a month.

I never thought, bitcoin would be just another scam! I know it is not but online exchanges like Tradehill should be shut down and removed if they keep destroying the whole idea of bitcoin.

If they don't have the currency to cash out, they can at least let me know!

Anyway guys, I am upset that I kept mining it bitcoins since more than 4 months, invested in a good hardware and now when my time came to cash out, it never worked! Please help and guide with a solution here. I would appreciate your help Smiley

Thanks.
