That is the reason I hold more Monero now.

It also need to change the PoW to attract more users to make it safer.

I hold it because it is the best anonymous coin and it has a good community and GPU miners can contribute to it.

That is right. I sold before, and the price kept on rise. Now I just hold.

How to disable the option dev fee?

That is right. I only stick with the famous coins.

Any further developments?

It is difficult to say. The Ethereum hard forked a few months ago. The combined value is much higher than before.

The price has risen over 25% in the last 30 days. It is a good performance.

It is fluctuating around 0.05 now.

If you do not have the ASIC, it is better not to mine the Dash. It is not GPU mineable for long time. You will lose money.

When there is enough supply in a few months, the ZEC price will reduce to between 0.1 to 1 bitcoin.

"Ransomware, which refers to malicious software designed to block access to a computer system or data until a ransom has been paid, has been around since the 1980s. However, ransomware attacks have increased substantially in recent years and are expected to increase as encryption software has improved as well as due to the increasing popularity of pseudonymous cryptocurrencies, such as bitcoin, which facilitate ransom payments for hackers.
According to the U.S. Department of Justice, ransomware attacks in the United States average 4,000 a day, while the ransoms usually range anywhere between $500 to $1,000, according to cybersecurity firm Cyence. Is the simultaneous rise of bitcoin and ransomware attacks linked together or is it just a spurious relationship? David Emm, principal security researcher at Kaspersky Lab, responded in a ZDNET article, "It's helping. […] The existence of effectively anonymized payment mechanisms definitely plays into the hands of cybercriminals."
Banks are not the only businesses preparing for cyber-attack using bitcoin. Citrix and Consensuswide found in a survey that one in three UK companies have started to stockpile digital currencies, including bitcoin, in order to pay for potential future ransomware attacks. Further, over 35 percent of larger firms, that is those with over 2,000 employees, would be willing to pay over £50,000 to regain access to business critical business data and intellectual property.

While ransomware attacks have traditionally primarily affected private individuals and small companies, hackers have stepped up their game and are now targeting large corporations, government entities, and even hospitals.
The rise in large scale ransomware attacks have also led some of the largest banks in the UK’s City of London to conclude that they need to start stockpiling bitcoin so that they will be adequately equipped to deal with these types of cyber-attacks going forward.
Dr. Simon Moores, chair of the Annual International e-Crime Congress and former technology ambassador for the UK government, stated that several UK-based banks are of the opinion that it is simply cheaper to pay off cyber criminals rather than risk an attack.
“From a purely pragmatic perspective, financial institutions are now exploring the need to maintain stocks of bitcoin in the unfortunate event that they themselves become the target of a high-intensity attack, when law enforcement perhaps might not be able to assist them at the speed with which they need to put themselves back in business.”
 
Industry experts such as leading cyber security firm Symantec, however, disagrees with this approach. According to the firm’s CTO Robert Shaker II, companies who pay ransomware attackers will end up “on a payer’s list,” which means other hackers will specifically target these companies with the expectation of also receiving ransom payments. Furthermore, paying the ransom in no way guarantees that the company’s encrypted data will be released again as hackers can easily come back and ask for more money or only release small amounts of affected data at the time. Symantec recommends not paying ransomware attackers. Instead, companies should have adequate data back-ups in place, acquire cyber insurance and consult a technology investigator in the case of an attack.
It is somewhat ironic that banks, who have mostly been very anti-bitcoin from the start as the use of decentralized digital currencies are a growing threat to their existing business models, are now hoarding bitcoins to mitigate potential future ransomware attacks. Instead of embracing the world’s only truly stateless and global currency, banks have dismissed it and have even closed down bitcoin businesses’ bank accounts as the threat of global bitcoin adoption affecting future banking profitability is becoming more tangible every day.
Whether the announcement that banks are potentially willing to pay off hackers in ransomware attacks will end up attracting more cyber attacks or not will remain to be seen."

"Christina Yee is one of the bright, young names in the cryptocurrency space. As Chief Brand Officer of Kraken, one of the world’s largest global bitcoin exchanges in terms of volume and liquidity, she plays a key, strategic role in furthering the company’s stellar reputation and commitment to clients.
Kraken has an extensive, growing client base of traders in US dollars, Euros, Canadian dollars, British pounds, Japanese yen and digital currencies like ether, all on an exchange that is widely reputed to be one of the best and most secure in the industry. Founded in 2011, Kraken has the distinction of being the first bitcoin exchange to go live with market data on Bloomberg Terminal, the first to complete a proof of reserves audit, a partner with the first cryptocurrency bank, and one of the first exchanges to enter into the realm of bitcoin margin trading.
Kraken’s crowning moment, however, took place in 2014 when it was selected to aid in the investigation and liquidation of Bitcoin exchange Mt. Gox, following the latter’s highly publicized demise. Kraken’s primary role has been to assist Mt Gox creditors in filing claims, identifying missing bitcoins and reconciling assets.
In an exclusive interview with BTCManager, Christina Lee offers a fascinating look at the circuitous path that landed her at Kraken as well as the company’s strategic evolution amid ongoing efforts to put closure on the Mt Gox case.
 
Christina, you began your career journey as a poker player before working in the advertising world. Tell us a little about this.
During college, I studied marketing and psychology and also became a professional poker player online. After graduating, because I was making such good money at poker, I decided to do it full-time and ended up moving to Las Vegas to play cash games at the casino. It was fun working for myself, being competitive and meeting new people. I found the experience invaluable when it comes to reading the body language of individuals, doing quick calculations and exploring Game Theory.
At the same time, there were aspects of teamwork and community found in a typical work environment that I missed. So I moved to San Francisco and went to work for an advertising agency that had a number of big technology companies as clients. As a strategist, I would meet with product teams and assess why they were falling short of the results they wanted to achieve. I’d then develop strategies to address this.
 
So how did all of this lead you to Kraken?
Great question [laughter]. After three years in the advertising world, I decided that it was time for a new challenge, something new and more exciting. Jesse (CEO of Kraken) and I had met at a networking event where we traded contact information. Bitcoin was already in my awareness as a result of a client debriefing from my advertising work. I found myself intrigued and did some deeper reading on it.
It was not long after that I talked with Jesse about my career exploration. He responded by saying, “with everything that you’ve done in advertising space, we don’t have anyone on our team that’s doing any of that. So it would be a great fit if you were to come to Kraken.” I interviewed with Jesse, the CFO at the time, and the team, and have been working non-stop since.  "
