Bitcoin\u2019s price has been swinging back and forth lately, which has also started affecting Bitcoin mining. The difficulty level of mining has fallen, and as a result the network now has little more than half of the computing power compared to its peak. For normal users this causes no harm, since the network still has more than enough computing power and Bitcoin\u2019s security remains excellent.\r\n\r\nIn other news this week we will look at how Bitcoin and the crypto community shows goodwill by combating the raging COVID-19 pandemic. The Red cross in Italy has started collecting bitcoin donations, while the crisis has forced a chess tournament to turn to blockchain. Despite uncertain economic times even institutes have growing interest for blockchain technology.\r\n\r\nWe are also happy to present the opportunity for interest accounts in Coinmotion, whereby you can earn interest on loaned cryptocurrencies.\r\n\r\nLast week\u2019s news can be found here.\r\n\r\n\r\nCoinmotion offers interest accounts\r\nCoinmotion, Finland\u2019s leading cryptocurrency service, has started providing the chance to earn interest on crypto investments. It is possible to earn interest by loaning cryptocurrencies onward. The interest account service is published in collaboration with Tesseract Investment.\r\n\r\n\u201cCryptocurrency lending markets have been developing rapidly during past two years, and with selected partners and development we want to offer possibility to earn interest on the cryptocurrencies that are otherwise under passive ownership or HODLing. It\u2019s dependent of course on the client risk preferences, if earning interest and bearing the counterparty risk is a suitable choice\u201d, says CEO of Prasos Heidi Hurskainen.\r\n\r\nBy using the interest account Coinmotion\u2019s customers can earn daily interest on loaned funds. The interest account service supports all Coinmotion\u2019s currencies apart from stellar.\r\n\r\n\r\nBitcoin\u2019s mining difficulty level plunged\r\nThe difficulty level of Bitcoin mining witnessed its second biggest single collapse during its entire history. On 26th March the difficulty level plunged 15.95%, rivaled only by a drop of 18% in October 2011.\r\n\r\nThe Bitcoin network automatically adjusts the mining difficulty level according to how much computing power the network has. The difficulty level is adjusted so that it on average takes 10 minutes for miners to find the next block regardless of the amount of computing power.\r\n\r\nThe decreasing difficulty level is probably related to last week\u2019s market chaos, when bitcoin\u2019s price dropped dramatically. Earlier an almost equal crash was seen in December 2018, when bitcoin\u2019s price also declined rapidly.\r\n\r\nDespite the decrease in mining difficulty, it practically has no notable effect on the Bitcoin network\u2019s security. Bitcoin continues to be the world\u2019s overwhelmingly biggest system for decentralized computing \u2013 and also the safest.\r\n\r\n\r\nA quarter of trading houses use blockchain\r\nEvery fourth trading house and institutional trading firm is using blockchain to some extent, reveals analysis firm Acuiti. The survey interviewed 86 leaders of major companies within the trading sector.\r\n\r\n26% of companies had some activity related to blockchain. 17% of traditional trading firms used cryptocurrencies in some form, meaning they either exchanged them for customers or owned them directly. A quarter of respondents had a positive stance toward crypto utilities.\r\n\r\nThe survey also indicated that most companies have interest to start using crypto. 45% of those who had no crypto-related activity planned to reconsider cryptocurrencies within six months. 97% in turn had plans to consider crypto within two years or sooner.\r\n\r\n\r\nBitcoin-friendly US senator infected by corona\r\nThe Bitcoin-friendly United States senator Rand Paul has been infected by the coronavirus. Paul is particularly remembered by the Bitcoin community for becoming the first notable US politician to accept bitcoin donations in his 2016 presidential campaign.\r\n\r\nPaul has earlier vocally supported the smallest possible regulation for cryptocurrencies. While admitting he does not know what the future holds for crypto, he considers them a great idea. He has also criticized fiat currencies, which according to him are just empty paper and won\u2019t last forever.\r\n\r\nAccording to the senator\u2019s office Paul has no symptoms and is feeling fine. The senator was put in quarantine right after confirming the infection. The corona test was done since Paul travels a lot, despite not having confirmed near contact with any other infected party.\r\n\r\n\r\nThe crypto community combats COVID-19\r\nThe Red cross in Italy has started accepting bitcoin donations with the intention of acquiring new medical equipment to combat the coronavirus pandemic. The first fundraising set a goal of collecting $10\u00a0000 dollars, which was exceeded in only three days.\r\n\r\nFollowing the successful campaign the Red cross has decided to continue accepting bitcoin donations. The goal of the new initiative is to acquire $26\u00a0000 dollars worth of necessary equipment for intensive care. At the time of writing over $20\u00a0000 dollars worth of bitcoins have already been donated.\r\n\r\nAside the donations the crypto community has also taken other measures in the battle against the pandemic. One example is that many crypto miners have transferred a notable portion of their computing power to the Folding@home project, which uses computing power to solve different medical and mathematical problems in order to find a cure for the virus.\r\n\r\n\r\nBlockchain can save a chess tournament\r\nThe coronavirus has also affected a major chess tournament in Jekaterinburg, the winner of which was set to meet world champion Magnus Carlsen. Like many other events, the tournament has been postponed without a clear date. Now the tournament\u2019s organizers are considering using blockchain technology to enable it by distance.\r\n\r\n\u201dWe are working on the anti-cheating engine that may record over one hundred data points for each move \u2014 its timestamp, players\u2019 biometrics, chess engine evaluation, etc. Storing this data in the decentralized database would make a lot of sense,\u201d reported Ilja Merenzon, CEO of World Chess.\r\n\r\nAccording to Merenzon the system has already been in development for some months and is likely to be published in the following weeks. World Chess is yet to reveal when the new tournament will be organized, but the world championship game is set to take place in November.
