Cryptocurrency: US ETrade Adopting, Central Stable Exch Gov... all Proven to be Shitcoins, again

https://www.bloomberg.com/news/articles/2019-04-26/e-trade-is-said-to-be-cl… https://twitter.com/nathanielpopper/status/1121868559330598912 https://twitter.com/TDAmeritrade/status/1121883679675101184 https://fnordprefect.de/ E*Trade Financial Corp. is getting ready to let customers trade cryptocurrencies on its platform, according to a person familiar with the matter. The firm will start by adding Bitcoin and Ethereum, and will consider adding other currencies in the future, said the person, who asked to remain anonymous because the matter is private. A spokesman for E*Trade declined to comment. This is said to be custodial / storage... actual coins... thus more direct than Fiat settled futures or tracking ETFs, and without Grayscale's NAV premium or Legacy Bank Brokerages blocking buyers, and likely with low trade fees. Offloading to private wallets is yet unknown. TDAmeritrade and Fidelity also in play. https://www.theregister.co.uk/2019/04/26/bitfinex_fraud_claims/ https://iapps.courts.state.ny.us/fbem/DocumentDisplayServlet?documentId=vIe… The price of Bitcoin has dropped seven per cent after New York's Attorney General accused leading exchange Bitfinex of trying to hide $850 million in missing funds. The accusation came in a legal filing [PDF] on Thursday that claims Bitfinex raided the reserves of Tether -- a digital currency that is kept at parity with the U.S. dollar in order to allow traders to switch easily between real and virtual currencies -- in order to make up the massive shortfall. Both Tether and Bitfinex are headquartered in the tax haven of the British Virgin Islands and, according to the NY Attorney General, are owned and run by the same group of executives and staff. Tether is a so-called "stablecoin" and the company claims that every Tether virtual coin is backed by a dollar held in reserves, the idea being that people can be assured of its stability. But last month, on March 4, the NY Attorney General notes that Tether changed that assurance to note that "every Tether is always 100 per cent backed by our reserves, which include traditional currency and cash equivalents and, from time to time, may include other assets and receivables from loans made by Tether to third parties." [...] As part of that investigation, the OAG uncovered documents that purportedly show that in mid-2018 Bitfinex didn't have sufficient real-world currency deposits to meet customer demand. All "stable" coins are centralized Fiat shitcoins. If it can be sued or shot, it's Fiat shit too. There are always degrees on continuum, but in the end... Not your keys, Not your coins.

And if such a sentiment as this were to take hold in the mind of the subject that would be the end of all security whatsoever"

Offst - A decentralized credit card
by realcr 25 Apr '19

25 Apr '19

Hi, I just published the first preview release of Offst. Offst is a decentralized payment system based on mutual credit. It's an open source project, written in Rust, licensed under AGPL3. You can find the release notes and more information here: https://www.freedomlayer.org/offst/offst-release/ Link to the project repository: https://github.com/freedomlayer/offst At this point Offst is only a bunch of command line tools, but I think some of you can already experiment with it. Criticism and ideas are welcome! real.
