The market turmoil that begun in last week is still going on, with bitcoin having seen the lowest price in over a year when the coin fell to nearly $3,700. Since then it has recovered, but it is still moving sideways on levels of about $4,000. Thus bitcoin has fallen about 80% of the all-time high it reached in last December. Most of the other cryptocurrencies have been affected as well, with most tokens seeing far lower prices than they did the same time last year.\n\nIt is of course impossible to say when the markets will change gears and begin to rise again, but there are at least some indications that it might happen sooner or later. For an example according to blockchain data, most of the sold bitcoins have been among the weak hand traders - those who are in for short-term profits. On the other hand those who have held their bitcoins for longer periods of time seem unaffected by the markets.\n\nThis means that sooner or later the sellers will run out. When that happens, the bitcoin price should start rising upwards again, as there are still people who want to buy bitcoins and holders who won\u2019t sell their own.\n\nIn the meanwhile we are looking on to some other news. For an example new studies have revealed that Bitcoin is secure and that blockchain could add even trillions of dollars worth of value to the global economy. On other news the ASIC manufacturer Bitmain is facing legal troubles and Ohio is going to give its businesses the ability to pay taxes with bitcoin.\n\n\n\n\u201cBitcoin sale\u201d has become somewhat of a meme in the global bitcoin community. Here an American restaurant is offering Bitcoin Roll for sale.\n\nNew Research: Bitcoin is Secure Against Attacks\n\n\nAssociate Professor Saravanan Vijayakumaran from the Indian Institute of Technology in Bombay has released a new research paper that concerns on the security of Bitcoin. The paper explores Bitcoin's security on three levels, how easy it is to steal bitcoin, can you tamper with transactions and is it possible to disrupt the system.\n\nOne of the main questions the research went on to answer to was Bitcoin's resistance against the so-called 51% attack. According to the paper 51% attack means "The ability of someone controlling a majority of network hash rate to revise transaction history and prevent new transactions from confirming." Few small cryptocurrencies have fallen to 51% attacks.\n\nAccording to the research Bitcoin is almost immune to 51% attacks. The hashrate securing Bitcoin is immense, which means that the possible attacker would have to use massive amounts of computing power and resources and they still could only get some minimal financial gains. According to the study, the attacker would also only only be able to insert or remove transactions, but not alter them or steal bitcoins.\n\n"While launching a 51% attack requires significant expenditure with little financial returns, it is not out of reach of a hostile nation-state. Until an adversary of that stature emerges, the Bitcoin protocol can be considered secure," professor Vijayakumaran commented.\n\n\n\nBitcoin is extremely secure: indeed, the most secure economic system ever created.\n\nWTO: Blockchain Could Add Trillions of Value\n\nThe World Trade Organization has released a new report on blockchain and how it could affect the international trade. The study looked on how blockchain could affect industries like trade finance, customs, logistics and such. It concluded that the blockchain could add almost $3 trillion worth of value on a global scale.\n\nAccording to the study blockchain could be used to automate many of the processes, to increase automation and help coordinate labour and logistics. According to the report the removal of barriers due to blockchain could result in more than $1 trillion of new trade in the next decade.\n\nMany of these potential blockchain applications are already either on development or even seeing their first use-cases. For an example blockchain has already been successfully implemented on monitoring the tracking of logistics and cargo.\n\n"Blockchain could make international trade smarter, but smart trade requires smart standardization - and smart standardization can only happen through cooperation. If we succeed in creating an ecosystem conducive to the wider development of blockchain, international trade could well look radically different in ten to 15 years," IMF states in the report.\n\nBlockchain could benefit international economy in many ways, from ensuring shipment to lowering the cost of international remittance.\n\nCopay Wallet Has Been Compromised\n\nA vulnerability has been found from widely used Copay wallet. A third-party code package used by Copay wallet and BitPay app was modified to load malicious code, which could steam users' private keys. The malicious code was deployed on both Copay and BitPay apps, but BitPay app was not vulnerable to the code. However Copay wallet was.\n\nThe company is looking into the issue and trying to fix it. In the meantime BitPay says that users of Copay wallets from versions 5.0.2 to 5.1.0 should not run or even open the application. A security update has been released and it is available soon.\n\nAfter the user has downloaded the update, they should create a new completely new wallet and move their cryptocurrencies there. They should not try to use any backup methods, but assume that the previous wallet is compromised.\n\nCopay\u2019s wallet is very popular, but the third-party packs it used were compromised and now many bitcoin users are affected.\n\nState of Ohio to Allow Paying Taxes With Bitcoin\n\nThe State of Ohio is going to set up an official website, which allows businesses to pay taxes with bitcoin, tells the Wall Street Journal. Currently the iniative concentrates solely on businesses and bitcoin, so individuals and other cryptocurrencies aren't yet included.\n\nThe previous attempts in U.S. to allow paying taxes with bitcoin has faced problems and the lack of political support. In February of 2018 both Arizona and Vermont tried to allow paying taxes with cryptocurrencies, but both attempts failed and were buried silently.\n\nOhio's attempt is different from previous attempts especially in the legal and political way. According to Ohio's State Treasurer Josh Mandel, his office doesn't need the approval from legislature or governor.\n\nIf the iniative is successful, it could help bolster the future official acceptance of bitcoin and help other states to create their own methods of paying taxes with cryptocurrencies.\n\nOhio\u2019s development could be beneficial for the cryptoadaptation as whole.\n\nBitmain Accused of Using Their Customer\u2019s ASICs\n\nOne of the biggest mining chip manufacturers and mining pools, Bitmain, is facing legal troubles. A lawsuit of over $5 million has been filed against the company, after it was accused of using the machinery its customers bought to mine cryptocurrencies for the benefit of the company.\n\n"In the past, Bitmain ASIC devices could be configured and initialized in low-power mode that did not mine cryptocurrency for Bitmain. However, after Bitmain established itself as one of the world's largest cryptocurrency miners in the last several years, defendant redesigned its ASIC devices to mine cryptocurrency for the benefit of itself rather than its customers who purchase the products. Conveniently, Bitmain cashes in on every second it takes to get the ASIC configured with the customers' specifications and lays the substantial costs of operating the ASIC devices at the feet of its customers," the court documents read.\n\nThe plaintiffs are claiming that Bitmain's new Antminer ASICs are extremely hard to configure, and at the entire time the user is making these configurations, the ASIC is running at full power and mining cryptocurrencies for Bitmain. This could be very costly, because of the high energy requirements ASICs need when running at full power. For an example the Antminer S9 requires about 1,375 watts of power when running on full mode.\n\nNonetheless because of the share size of the case, it could take ages to come into fruition. Currently there are more than 100,000 plaintiffs. Because of the practical limitations, the legal representatives of customers are working on certain criteria to limit the filing to just over 100 individual cases.\n\n\n\nBitmain is one of the largest mining institutions in the world, but in many ways also the most controversial.

For an example among two of the best profiters of the week of market turmoil are Bitcoin Private and Ravencoin, both of which are mainly copies of Bitcoin.\n\nDuring the last seven days period Bitcoin Private has risen almost 40%, most during the beginning of the week. Ravencoin on the other hand has gained 18%.\n\nEven though cryptotokens like Ravencoin and Bitcoin Private have the potential to make huge gains in little to no time, it is unlikely that any of the Bitcoin forks will prevail. None of these forks offer any real benefits over Bitcoin. If there is something in them that is better than Bitcoin, it is marginal at best and on most other fields Bitcoin trumps them.\n\nFor investor who is interested in alternative cryptocurrencies, it is usually a safer bet to invest in something that is actually different from Bitcoin and not just an inferior fork.\n\n\nMost of the forks are done just for the sake of forking, without actually offering anything of value.
