Chinese digital currency exchange OKCoin has stopped accepting US dollar deposits, a move it attributed to banking issues.OKCoin becomes the latest cryptocurrency service to report problems with USD transfers, coming just a day after Bitfinex revealed that it, too, wouldn’t be able to accept transfers, citing correspondent bank problems that initially focused on outgoing wires.When reached, an online support staffer for OKCoin told CoinDesk that the exchange currently doesn’t have an exact timeline for reactivation.The exchange told users yesterday that it was working to restore deposit functions through alternative channels."Please do not make further deposits as your wires may be rejected by intermediary banks," a notice posted on the exchange’s website stated.The move comes months after OKCoin, as well as other exchanges based in China, shifted policies in light of new regulatory scrutiny and later froze bitcoin and litecoin withdrawals pending upgrades to their systems.That state of affairs continues, a situation local sources have attributed to ongoing discussions with the People’s Bank of China (China’s central bank) and other regulators in the country.

It also follows the release by OKCoin of beefed up anti-money laundering/know-your-customer requirements on 10th April.Other exchanges have reported transfer holds as well, though how the developments are connected isn't immediately clear.Crypto-exchange BTC-e, for example, said that it wouldn’t accept international transfers in USD for the next month, citing a shift to a new bank account in a post on Twitter from 14th April.bitcoin asic usb minersOKCoin Jump to: navigation, search OKCoin is a Bitcoin company in China with core product lines of a Bitcoin exchange, and a mobile consumer payment and lending app.chromecast bitcoinOKCoin Exchange China operates CNY/BTC spot pair with margin trading from its Beijing entity, while OKCoin International operates USD/BTC spot pair with margin trading and BTC/USD futures from its Singapore entity.bitcoin nasil kullanilir

As of August 2016, OKCoin is the largest Bitcoin exchange in the world with a volume of over 16,000,000 Bitcoins per month.[1][edit] OKCoin was founded by CEO Star Xu in 2013 and has raised US$10mm in investments from Ceyuan Ventures, Mantra Capital, Ventures Lab and other notable private investors including Silicon Valley investor Tim Draper. – a popular file sharing company – where he managed a team of 120 engineers.[2][]OKCoin has publicly expressed intention to expand overseas and become a worldwide digital currency services company.[3][]OKCoin management claimed that they could no longer pay Ver the money which was contractually owed to him due to a recent case in which Ripple Labs was fined $700,000 by FinCEN for failure to collect proper KYC paperwork from Ver.[5]In response, Ver published several months of email history between himself and OKCoin demonstrating that OKCoin had not been making payments for several months prior to the news about Ripple's fine.[6]In the emails, OKCoin CEO Star Xu claims to have discovered a more recent version of the contract signed by both parties, which included a clause that gave OKCoin the right to terminate the contract upon six months notice.

Until this point, all communications between the two parties had been cryptographically signed using GPG, but Ver was able to prove that the newer version of the contract was signed with the same timestamped signature he appended to the previous version of the contract, indicating that his signature was merely copied over to the new document.[7]OKCoin proceeded to make a public offer of a $20,000 reward for anyone who was able to prove that Ver's statements were false; Ver responded in kind by offering a $1,000,000 reward to anyone who could prove that the signature on the more recent contract was actually valid and not a forgery.[7]The OKCoin reward was paid at the end of May, 2015 following the report of analysis of the contracts posted publicly by OKCoin.[8][edit] ^ ^ ^ ^ ^ ^ ^ a b ^WarningYou are using Firefox 43, which is known to crash when using Cryptowatch.Mozilla has fixed this issue in newer versions.Download the Firefox Nightly build for a more stable experience.

Google Chrome is another good alternative.SHANGHAI Two of China's three largest bitcoin exchanges said they were taking measures to stop withdrawals of the cryptocurrency from their platforms, as capital outflows prompt the Chinese central bank to step up its scrutiny of the industry.OkCoin and Huobi said in statements published on their websites late on Thursday that they would halt withdrawals of bitcoins completely, while the other big exchange BTCC said it would subject withdrawals to a 72-hour review.Earlier in the day, the exchanges had issued statements saying they would strengthen oversight of customers' identities and sources of funds.They had also said they would upgrade their anti-money laundering systems, but that withdrawals of Chinese yuan would not be affected.These measures come after China's central bank said it called nine of the country's smaller bitcoin exchanges in to a Wednesday meeting to discuss risks in the bitcoin market, and warned them they risked closure if they seriously violated regulations or took part in activities such as margin lending.

Bitcoin prices on European exchange Bitstamp were down 0.8 percent on Friday, trading at $975.61.Beijing signaled it was keeping a closer eye on the bitcoin industry last month by launching checks into BTCC, Huobi and OkCoin, amid growing government efforts to stem capital outflows and relieve pressure on China's currency, the yuan.While the yuan weakened 6.6 percent against the dollar last year, its worst performance since 1994, the bitcoin price has soared to near-record highs.]That, and the relative anonymity the digital currency offers, has prompted some to believe bitcoin has become an attractive option for tech-savvy Chinese to hedge against the yuan and skirt rules limiting how much foreign exchange individuals can buy each year.BTCC, Huobi and OkCoin last month stopped margin lending and introduced trading fees after the People's Bank of China (PBOC) launched checks into them.In their Thursday statements, they also said they may freeze assets or limit trading by users who were found to flout rules.

The statements contained links to documents published by China's banking regulator warning investors about market risks.News of meetings between the various exchanges and the PBOC, and other government agencies has caused the bitcoin price to swing wildly.On Wednesday, the price fell from a one-month high after sources at bitcoin exchanges in China said the PBOC had summoned some exchanges to a closed-door meeting, before recovering all of those losses in U.S.The PBOC said the nine exchanges involved in the Wednesday meeting were CHBTC, BtcTrade, HaoBTC, Yunbi, Yuanbao, BTC100, Jubi, BitBays and Dahonghuo.Industry insiders said the majority of these exchanges allowed other cryptocurrencies to be traded on their platforms besides bitcoin.BtcTrade, Bitbays and BTC100 declined to comment on the meeting.Reuters was unable to immediately reach the other six platforms for comment.The Chinese actions will ultimately be good for the industry, said Charles Hayter, Chief Executive Officer of London-based digital currency analytics firm Cryptocompare."The
