    I’ve lost ~0.38 BCH because of local.bitcoin.com

    Posted: 02 Jul 2019 10:53 AM PDT

    EDIT:

    PROBLEM SOLVED, support from local.bitcoin.com was amazing!

    On the last Saturday (June 29) I tried to sell ~0.38 BCH using local.bitcoin.com.

    I had an open SELL offer and someone started a trade to buy it from me. I only had 0.2 BCH in my Wallet, so I sent some Dash to Changelly and exchanged to BCH.This is the transaction from Changelly to local.bitcoin.com Wallet -> https://explorer.bitcoin.com/bch/tx/998e30f047b7f04e36669c5a13294dbbe8c0260c9094186b6fa0c2c0de1d1eb3

    When I saw that my balance was updated, I tried to fund the escrow, but the website showed me an error message saying that my balance was not enough, which was weird since trade was for ~0.38 and my wallet was showing ~0.4.

    After seeing the error, I canceled the trade, but the BCH never went back to my wallet, now the trade amount seems to be parked on this address (https://explorer.bitcoin.com/bch/address/39JfzFu7wW5rUGjSXp1jJjvcvLdsNRVHiW) and my wallet balance is 0.052, which is from the address that received the change from the transaction that funded the escrow (https://explorer.bitcoin.com/bch/tx/fd491f5fdffcbc3f28d7891e9b19ea1e6a78f8f484794d1f463315ac2c3d89be).

    How can I recover my money?

    Thanks for the help.

    What’s the best travel site we can pay in BCH?

    Posted: 02 Jul 2019 10:23 PM PDT

    Some of the BCH accepting sites seem to be more expensive than traditional sites. Is there a BCH accepting site that's also price competitive?

    Not your keys, not your coins! The biggest Norwegian cryptocurrency exchange bitcoinsnorway.com says funds have been stolen because of a vulnerability in the AlphaPoint software and it will sell all its cryptocurrency holdings and send fiat equal to customers balance from may 7, 2019.

    Posted: 02 Jul 2019 05:37 AM PDT

    This exchange was the biggest in Norway and a traditional exchange in terms of having orderbooks and customer funds both fiat and crypto and they had Bitcoin, Bitcoin Cash and Litecoin, with fiat currencies NOK, USD and EUR.

    All the news about this is so far only in Norwegian but I can help with some translation and summarize this.

    Yesterday all customers in Bitcoins Norge / Bitcoins Norway got an email regarding attacks on may 7 of 2019 because of a vulnerability in the AlphaPoint software that somehow AlphaPoint had informed them about and yet they continued operations until July 1, 2019 before deciding to close down the exchange as AlphaPoint was unresponsive in solving the issue. You can read the email in full on their facebook page where they have also published it, although its in Norwegian only: https://www.facebook.com/Bitcoinsnorway/posts/2384228571620303

    Big Norwegian online newspapers have written a lot about this case so far (source https://www.reddit.com/r/BitcoinNO/comments/c7x0j7/dataangrep_på_alphapoint_bitcoins_norge_kunders/esiccn9):

    BTC Lightning Network -vs- BCH Coffee Shop simulation

    Posted: 02 Jul 2019 06:24 PM PDT

    TLDR;

    View this gist. It's a python program that runs through various TXN simulations to compare fees of various coins and wallets. Rates are based on late June pricing. Jump to Results section below.

    Lighting network simulator

    This is a very simple python program that will simulate a few conditions. For the ground work lets set up an Alice and Bob story.

    Bob's friend Alice sets up a coffee shop. She is going to start taking cryptocurrency at the coffee shop, so she is set up to accept Bitcoin Cash (BCH) and Bitcoin Core via Lightning (BTCLN). Bob has a substantial holding in both BTC and BCH, though it is all in cold storage in a HW wallet. He does have a Coinbase account but is always very careful to calculate trading fees. So now Bob wants to determine what would be the best way to get ready to move his daily coffee patronage to Alice's shop.

    Looking over his past expenses on morning coffee, he decides that 20,000 satoshis (BTC) should be a nice round number for lattes and perhaps 19,000 for coffee. Since BTC is trading at $10,600, his budget in terms of fiat comes out to just about $2 a day. With his budget in hand, he goes about reviewing the BCH and BTCLN payment options. He suspects BTC (mainnet) is too costly since he doesn't want to leave Alice with low priority economical transactions to chase.

    Bitcoin Cash

    His simplest solution of course is just to move BCH from his HW wallet (cold) to his mobile wallet (hot), but he wants to keep his BTC and BCH accounts fairly balanced and doesn't want to deplete his BCH funds entirely. He also wants to pay Alice in both BCH and BTCLN since she seemed excited about her new Point Of Sale system. He had thought about converting some of his BTC to BCH, though he realizes that there is always a cost for this on Coinbase (usually 0.15%).

    Eclair LN Wallet

    The next wallet Bob looked at was the Eclair mobile LN wallet. This would be simplest to fund with BTC which of course would have costs in moving funds from his HW wallet to Eclair, and then even more costs opening and closing a channel. He also noted on the github for the project that many LN wallets do not allow fees to be set on channel close operations. This might get costly as market fee rates rise.

    Wallet of Satoshi, funded by a BTCLN exchange.

    Another popular LN solution is Wallet of Satoshi (WoS). WoS seems like a simple solution since it doesn't have the same constraints on incoming and outgoing capacity like Eclair does. There is also no need to do any complicated channel setup since it is custodial and that is all just handled. Bob does realize that WoS funding options might be costly. He researches ways to load and unload WoS using the FixedFloat exchange as well as the bitrefill Thor channel services.

    FixedFloat for BCH funding and withdrawals from WoS

    As noted before with WoS, LN transactions are seamless enough, but WoS has no way to convert funds back to BTC. For this we have to use a LN exchange. FixedFloat is a fairly reasonable exchange offering competitive exchange rates and a 0.5% fee. To convert funds from BTC, WoS has offers a comptitive rate of 0.3%, so obviously this is the simplest way to fund the wallet.

    Bitrefill for BTC funding

    Although not a verify competitive option, the Bitrefill funding option is included here just to see how it stacks up to the others.

    Results

    I've included two runs of the simluator in LibreOffice format. They should be viewable in Google Sheets, Excel or LibreOffice

    Latte (without bugfix)

    This simulated buying lattes (20k sat) and compared the cost of using various wallets. Important inflection points that were found:

    • 17 cups / 3.6 mBTC - If spending less than 3.6 mBTC, it is cheaper to convert the BTC to BCH and just use a BCH wallet. At 17 cups however, using the WoS LN wallet is the cheapest way to spend BTC.
    • 39 cups / 8.0 mBTC - If spending less than 8.0 mBTC, it is cheaper to fund your WoS LN wallet using BCH. At 39 cups it becomes less expensive to use BTC to fund your WoS LN wallet.

    Coffee (with bugfix)

    This simulated buying coffees (19k sat) and compared the cost of using various wallets. Important inflection points that were found. This simulation did assume that the expensive channel close bug in Eclair was fixed:

    • 4 cups / 1.9 mBTC - If spending less than 1.9 mBTC, it is cheaper to convert the BTC to BCH and just use a BCH wallet. At 4 cups however, using the WoS LN wallet is the cheapest way to spend BTC.
    • 41 cups / 8.0 mBTC - If spending less than 8.0 mBTC, it is cheaper to fund your WoS LN wallet using BCH. At 41 cups it becomes less expensive to use BTC to fund your WoS LN wallet.
    • 853 cups / 163 mBTC - If spending less than 163 mBTC, the average TXN cost of using BCH is cheaper than using BTCLN. At 853 cups however (yikes), it is cheaper to use BTCLN for coffee than to use BCH.

    Files
