The company failed to complete an annual report for 2015. When it shut down in 2016, "an internal audit showed “a deficiency of bitcoin" in company wallets" which suggests improper storage and security practices. As of 2017, official statement was that NewNote owed nothing to creditors because the issue was with CoinTrader. No...")

The service launched in 2014, and by March of 2015 there was no response to requests for withdrawals. Roughly $1m USD was pocketed by the CEO.

• 14:44, 24 January 2023 Azoundria talk contribs created page Allcrypt (Created page with "{{Imported Case Study|source=https://www.quadrigainitiative.com/casestudy/allcrypt.php}} It’s always fascinating to hear about an essentially anonymous exchange operator who secured the exchange only with Wordpress, taunted hackers on Twitter, and then was rude to customers after the fact. Luckily, this exchange didn’t achieve any significant volume, which is not surprising. Had they invested in a simple multi-sig cold storage wallet, all could have been avoided. T...")

While we can look back and see this as a Ponzi scheme, the key issues at the time include a lack of knowing who’s behind the operation, lack of any sort of registration, and no visibility into the financial status of the exchange. An environment wh...")

The customer legitimately requested the withdrawal and failed to notice the changed address. “796” appears to have handled this well, and the situation was quickly made right. No other customers appear to have been affected. It is sugges...") Tag: Visual edit: Switched
