Chainalasys VS Mycelium - The full story

Mycelium Wallets use our own custom nodes to process the bitcoin blockchain and scan for address balances. These nodes were written by Jan Møller while he was the Lead Developer, along with our other devs. The job of these nodes is to parse the 30 gig Blockchain database into our own custom database, which is much larger, being over 100 gigs in size, but which allows for very quick and easy lookup of address balances, allowing for instant balance lookups and to do things like Cold Storage spending from paper wallets and Trezor. Note that this custom database doesn't actually contain anything that's not in the original blockchain database itself.
Mycelium's owner and developers believe in total financial privacy and personal freedom, and our company has a goal to make Mycelium Wallet the most anonymous wallet possible. For this reason, we have kept our wallet code completely open since the beginning, and have been public and open about what goes on internally in our company (I hope you have noticed my frequent updates, especially with the unfortunate Entropy delays). And even while Jan was still the lead dev, we have created LocalTrader to work completely anonymously, using only bitcoin signed messages for user authentication and encrypting all user chat P2P using their respective private keys so our servers receive no usable data. We have also added HD wallet support, and disabled all IP and transaction logging on our nodes. However, we also realize that just us claiming that we do that isn't good enough, and that's why we added full Tor support, and are in the process of implementing CoinJoin, which we hope to have enabled by default, so that even those who don't care about staying anonymous will help contribute. Our goal was to have Mycelium Wallet be as anonymous as Dark Wallet, and that has not changed.
Jan Møller, our lead developer who did most of the work on the nodes, realized that the node-parsed blockchain database can be used to analyze bitcoin transaction activity, and help track transactions in the same way that our current financial institutions do (although with much less certainty). So he decided to have his own project that does just that, and has split off from Mycelium company last October. We still kept him on as our chief technical consultant, since he did write most of the node and original wallet code, so he is technically still employed by Mycelium, but he has had no access to our nodes since he left. Our current full time lead developer is Andreas Petersson, who is working on implementing Coinapult Locks right now, and the other two developers are Jan Dreske (trasla here) and Daniel Weigl, who have been adding support for Trezor, fixing bugs, adding minor requested features, etc.
We at Mycelium are not fans of what Chainalysis does, but we can't really object too much, because if something like this is even possible to do, then someone will do it, whether it's Jan's company or someone else. It's also preferable that this is done by a public company in the open, instead of in secret by a government agency. And secondly, since the developer behind this is someone who worked with us and continues to stay in touch and advise us, we can at least get inside knowledge of what may be tracked and how by such systems, so we can be aware of what to watch out for and what to fix. Obviously it's not a guarantee that we will get an honest answer, but it's still better than nothing.
With regards to why our website's About section still lists Jan Møller as a Lead Developer, it's because our website dev has been working full time on another (secret) Mycelium project, and has not had the chance to change anything. I guess the site is too low of a priority to update. Note that both of our current top wallet developers who have been doing most of the work these past few months, Jan Dreske and Daniel Weigl, are completely missing from there too. I am sorry that I have not publicly stated anything about this either, but since Chainalysis is a completely separate company, Jan Møller has not had access to our internal systems since he became a consultant, and our internal goals are still total anonymity, there was no risk whatsoever to Mycelium or the privacy of our users from the Mycelium side. I have been fairly open about being an AnarchoCapitalist myself, supporting people like Cody Wilson and Ross Ulbricht, and supporting the idea of The four pillars of a decentralized society as explained by Johann Gevers to help decentralize government functions. So if there ever is a risk of Mycelium becoming a snooping agency, or if Mycelium changes its goals with regards to expanding personal freedom, I still promise to let the community know, since there would be no way I would be willing to continue to work there if that happens.
P.S. Yes, we have those Chainalysis nodes blocked on our Mycelium nodes, too, but that's not really a fix, since Chainalysis can just change their IP address.
EDIT: Also, please note that if Mycelium wanted to be involved in this, we would have done this internally ourselves, likely making a ton of money from bankers and regulators in the process. But we didn't, not even allowing Jan to work on this internally, and wouldn't even consider implementing anything like that.

Vienna, Austria set up the world's first specialized Bitcoin Bank

The world's first specialized Bitcoin Bank was established in Mariahilfer Street, Vienna, Austria, where an Austrian English news website has been reported.
The owner of the bank is a chain-based start-up company in Berlin, which is called Bit Trust Services, which is called Bitcoin-Bank. The purpose of this bank was to make it easier and simpler to sell Bitco.
The bank's ATM (ATM) can carry out two-way exchange between Bitcoin and Euro. The bank also provides information on virtual currency.
Magdalena Isbrandt is the general manager of Bit Trust, where she broadcasts to the local media, where digital currency trading is faster than other deals and no intermediaries.
"Value and currency can be sent directly from the user to the user," she said.
Promote the advantages of Bitcoin
The main advantage of digital money is that it has some degree of anonymity, says Andreas Petersson, co-founder of Bitcoal Austrian.
"If I pay Bitcoin online, I can protect personal privacy to some extent," Petersson said, and businesses will not get their credit card information. When buying digital assets like computer games, consumers will not have the feeling of handing out their private information.
The development of Bitcoin in Vienna
Three years ago, Vienna had deployed the first bit-currency ATM machine, which currently had at least 20 merchants willing to accept Bitcores, ranging from restaurants to pubs and bars.
According to Bit Trust's website information, the company is not just investors in Bitcoin and Block Chain companies, it has further developed a new concept in this area.
The company provides services such as Bitcoin ATM, payment system, prepayment prepaid card and other services.
