What is a replay attack?



Bitcoin Gold was successfully launched last week, but there are still many technical issues. If you still remember our previous article, the most critical one is the lack of replay protection. Do note that the coming Bitcoin SegWit2x hard fork in November also doesn’t possess such protection. Anyway, that’s why this week we are going to talk about how a replay attack works and what we should do to protect our funds.

So how does a replay attack works?



A hard fork on a blockchain is essentially creating a new incompatible blockchain which shares the same history with the legacy one, but has different blocks in the future. As they share the same history, if you hold some legacy coins during the fork time, you will also automatically gain the same amount of new coins. This distinctive feature opens rooms for a replay attack.



Normally when you send out Bitcoin, you are signing a transaction with your private keys (therefore never disclose your private keys to anyone) and broadcast that transaction to the blockchain. After a hard fork, both of your coins are stored on the same address, which means that they are controlled by the same private keys.

Without a replay protection, when you, say send out 1 Bitcoin from the legacy chain, the transaction is also valid on the forked chain with the same amount of new coins and same recipient. Someone else can make use of this and send out your new coins without your agreement. This is the same case for the opposite direction: when you send out the new coins, you are potentially also sending out your Bitcoin!

What we should do to protect our funds?

Basically wait for the implementation of replay protections. The previous Bitcoin Cash hard fork achieve this by modifying the signing mechanism so that we can distinguish the transactions from different chains. Bitcoin Gold claimed to implement the protection before launching, but the issue is still not resolved up till now.

While there are tricks to safely send out Bitcoin without a replay protection, like adding a small amount or coin mixing, this article is mainly for beginners and we do not recommend users without much experience to risk trying them as a single mistake can be disastrous. Instead, keeping the coins on your wallet and wait for further updates from the Bitcoin Gold team is the safest choice.

We at Cryptomover will keep following the latest updates and split the coins for our customers as soon as possible. As we stated, any new coins from hard forks will be part of your portfolio and we do not intend to charge anything from them. Please do remember to follow us for further updates!

The article is extracted from our medium blog post.

As mentioned in our previous article, the Bitcoin Gold hard fork will take place on 25 Oct, and everyone should have an idea about how to safely prepare for it!

Key summary:

• The safest way is to keep your Bitcoin on a wallet where you have the control to the private keys. It can be desktop wallets like Electrum or Exodus, or hardware wallets like Ledger Nano S and Trezor.
• Avoid moving your Bitcoin on that day, and also after the fork to wait for everything to settle.
• When the fork is settled, each wallet provider would provide instructions on how to claim your Bitcoin Gold on the specific wallet, but we will also have tutorials about it, please stay tuned!

Why should I move to wallets where I have the control to the private keys?
To put things simply, when you have control to your private keys, you are 100% guaranteed to have the forked coin. The problem is just how to split them on the wallet.

However, if for example your coins are stored on an exchange wallet, they have the rights to decide whether to issue the new coins to you or not. Anything can happen but you lose the control of it.

Why is this so important? Because Bitcoin Gold and Bitcoin will share the same address at the beginning, so when you have the private key, you can control the coins on that address. Even if your current wallet does not support Bitcoin Gold, you always have the option to import the private key on other supporting wallets to claim them.

Why should I avoid moving my Bitcoin after the fork?
As mentioned in another article, a hard fork is not compatible with old versions of the protocol so the network might be unstable during the time. However, more importantly, Bitcoin Gold does not have a Replay-Protection, which can be a huge issue.

Again, to put it simply, a replay attack means when Alice sends Bitcoin to Bob on the Bitcoin blockchain, Bob can also claim that Alice has sent Bitcoin Gold to him and “steal” Alice’s Bitcoin Gold. This is the same when Alice sends Bitcoin Gold to Bob, he can steal her Bitcoin. To avoid this, the previous Bitcoin Cash hard fork has implemented a replay protection, but this is not the case for Bitcoin Gold. Although they claim to be developing a strong replay protection, there are not any updates yet so it is better to wait and not move your Bitcoin shortly after the fork.

So what to do now?
Whether you are bullish or bearish on Bitcoin Gold, you should not lose your coins due to careless mistakes! Therefore, the best thing to do right now is following the summary above: send your Bitcoin to a wallet with control to your private keys, and wait until the fork is settled. Also don’t forget to follow us for future updates!

This article might not be related to Bitcoin at the time being but since Bitcoin might adopt smart contracts in the future, it would be worthy for beginners to understand what it is.



For traditional vending machines, you feed in coins and they will give out your choice of drink/food. Smart contracts are nothing different from this, but instead they are pieces of codes which allow more customisations and utilities.

Smart contracts on the blockchain will execute what they have been written for, and everyone can check it. Hence, unlike a vending machine which we have to trust that it actually holds enough drink or coins for changes, the smart contracts can be verified by anyone and so it is a trustless way of executing a contract.

Why are they useful?



Ethereum is the first platform that promotes smart contracts. On the platform, users can code a smart contract for different purposes: let the contract to hold some balance of coins, or to secure a transaction, or even ask it to trigger another smart contract under a specific condition.

The chain reaction of smart contracts can be very powerful and can create decentralised applications (Dapps) in which everything is executed on the blockchain. A list of applications built on Ethereum has shown that they can have impact on different industries, and the limit is really up to our imagination.

After all, smart contracts are the next generation of “vending machine” which do not require users’ trust and can run exactly for their purposes. Their flexibility also opens up for millions of possible innovative applications. They would play a main role in the future of blockchain technology and hence everyone should have an idea about what it is and how it would impact the the future development.

I have added the sources. Thank you for reminding!

We will rebalance the C10 index monthly, and replace coins falling out of the top 10 by new top 10 coins. In this way we can ensure to constantly have a market exposure of the top 10 coins weighted by market cap. This is a standard industry approach in the traditional finance world.

What is Bitcoin Gold?

At the beginning of the year it was only Bitcoin, August onwards we have Bitcoin and Bitcoin Cash and it looks like November onwards we will have three different versions of Bitcoin. The Bitcoin blockchain is set to go through a second hard fork on 25th Oct giving birth to Bitcoin Gold (BTG). Existing private key holders of Bitcoin balance at the time of fork will be credited with an equal amount of Bitcoin Gold on November 1st, similar to the way Bitcoin holders received dividend during the birth of Bitcoin Cash.

The team of developers, miners and other key contributors to the project is led by Jack Liao, CEO Of Hong Kong mining firm LightningASIC. He is accompanied by Chinese mining tycoon and owner of Jinse.com (Bitcoin news portal) and, the project’s anonymous lead developer that goes by the name of H4x3rotab. The fork aims to protect Bitcoin ecosystem by creating a totally decentralised Bitcoin. The fork is another battle between the mining cartel and Bitcoin’s core developers. At one hand mining cartels are seeking for more hashpower, while at the other hand Bitcoin’s core developers are working towards decentralization.


The project developers hope to open up mining to more participants by replacing the Bitcoin’s mining algorithm with the one (Equihash) that enables mining via GPUs. Zcash uses the same algorithm, and it is resistant to ASIC chips. Bitcoin Gold will therefore compete with Ethereum for mining hardware, despite being closer in design to Zcash. It appears to be a smart move as Ethereum project is planning to switch its Proof of Work mining algorithm to Proof of Stake in 2018. Bitcoin Gold has also altered its difficulty adjustment, of which their blockchain will measure and adjust the difficulty with every block found.

The project still has a lot of roadblocks to cross before it reaches the proposed fork. The team has yet not released the mining software, mining pool and block explorer, further the project doesn’t have a wallet yet. The biggest criticism of the project is the developer’s decision to mine the new blockchain themselves for some time after the fork — thus keeping all the mining rewards. H4x3rotab mentioned on the project’s slack channel that the number of blocks they plan to mine would not be more than one percent of the total supply.


Despite the talks of hard fork, China banning the Bitcoin exchanges & ICOs and recently South Korea also banning the ICOs, the price of Bitcoin has managed to keep up to 4300 levels. The news flow followed a two to three weeks of huge volatility in cryptocurrency space but the price of Bitcoin recovered and recently crossed the 4500 levels. The fork doesn’t look to have a major impact on the Bitcoin price. However it is interesting to note that Bitcoin Cash has been tanking down quite a lot in last few weeks. After the fork Bitcoin Gold will become a new member of Cryptomover’s Bitcoin Forking Index. It would be interesting to watch if Bitcoin Gold can have an entry similar to Bitcoin Cash. It would highly depend on how many versions of Bitcoin will market look to adopt and, if the intentions of Bitcoin Gold are genuine.

Good Luck Bitcoin Gold

Hi there! It is an article from our medium blog We also hope that this can be useful for newbies

What is a fork?


In open source software development, a fork refers to the event of an independent project spinning off from the original project by copying the code base and develop in a different direction.

This happens when the community has a diverse and irreconcilable visions/plans for the future development of the project. For example, Litecoin is a fork from Bitcoin because its developers copied the code of Bitcoin and launched as a separated project.

Due to the distinctive feature of blockchain that it relies on the entire network to run the exact same protocol, there are two kinds of forks: soft fork and hard fork.



What is a soft fork?

New rules by a soft fork allow a subset of the previous valid blocks, therefore all blocks considered valid by the newer version are also valid in the old version

A soft fork is forward compatible, meaning that old versions of the protocol will recognize new blocks. If at least 51% of the hashing power shifts to the new version, the system can self-correct and maintain consensus on the blockchain. For example, the Bitcoin SegWit upgrade on 21 Aug 2017 was a soft fork when the majority of the miners agreed to shift to the new version of the Bitcoin.

What is a hard fork?

Hard forks ease block acceptance rules making previously invalid blocks valid in the new version, therefore effectively creating a new blockchain

A hard fork is not forward compatible on the contrary. Old versions of the protocol are not compatible with the new versions and therefore it requires everyone on the network to upgrade. The risk is that when a substantial amount of miners refuse to upgrade, a chain split is very likely to happen. For example, the creation of Bitcoin Cash on 1 Aug 2017 was a hard fork from Bitcoin when the Bitcoin Cash developers disagreed with SegWit and decided to move onto the new blockchain.

Understanding the nature of forks is essential to keep track of the future development of Bitcoin and other cryptocurrencies. For example, both Bitcoin and Ethereum is going to have a hard fork soon. We will keep updating with regards to different forks, please stay tuned!

It's very difficult to predict the price movement so a long-term passive investing strategy might be better

There are also many chat groups on telegram, slack, skype, and discord etc. You can easily google them and join your favorite ones.

Indeed, for short-medium term store them in desktop wallets like Mycelium and Electrum, while for long-term holding its better to buy a hardware wallet like Trezor and Ledger. Paper wallets are a bit more difficult to create and keep but its a cheaper alternative to hardware wallets.

Different wallets support different coins. You can simply visit their websites to see what coins do they support

It's generally safe to just invest in the top 2 currencies, Bitcoin and Ethereum. However, if you resist selling at any moment, there can be a risk: you don't know what will happen in the future: the price might crash to the bottom, or some new technologies might be replacing those 2 coins. Therefore, I think a better strategy would be slowly selling a portion of your position when the price rises so that whenever something bad happens, you have already cashed out part of your positions and be safe.

You can donwload Electrum and store your coins there securely. For more advanced security you can also create a paper wallet with it until you receive your ledger

Bitcoin is still too volatile to be a currency. Imagine a merchant is pricing an item with Bitcoin... he or she would need to adjust the price everyday to keep up with the market price, which is not realistic and no one would want to do this.

While you should not 100% trust anyone, it's worth to read blogs written by the others when you are doing your research as they are easier to understand and allow you get an idea quickly. However, do try to read the opinions on both sides (buy/sell) and do your own judgment. When you are digging deeper in this field, it's also worth to learn more about the technical aspects, and read whitepapers/ github codes by yourself. This will provide you greater insights in certain technologies/ new coins and you will be able to have better judgment. Most ppl don't read and just follow opinion leaders, and they will hardly be successful.
