Why browser based cpu bitcoin miner I have to complete a CAPTCHA? Completing the CAPTCHA proves you are a human and gives you temporary access to the web property.
What can I do to prevent this in the future? If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Another way to prevent getting this page in the future is to use Privacy Pass.
Since December, bitcoins can not only be traded at more or less dubious exchanges, but also as futures at the CME and CBOE. And already several trading systems popped up for bitcoin and other cryptocurrencies. None of them can claim big success, with one exception. There is a very simple strategy that easily surpasses all other bitcoin systems and probably also all known historical trading systems. A buy and hold strategy works extremely well when a price bubble grows, and extremely bad when it bursts. They break the link of money and debt.
Cryptocurrencies don’t require the bank credit mechanism for money creation. They can be used where normal money would be impractical, such as fee transfers between machines or trading in multiplayer games. They allow low-cost and anonymous money transactions. They replace banks for storing and mattresses for stashing money. I’m ready to believe that blockchain is the future of money transfer and storage. But that does not mean an ever-rising bitcoin price. Hundreds of cryptocurrencies came out in the last two years, any single of them with a better blockchain technology than bitcoin, and any good programmer can add a new coin anytime.
Countries or big companies might sooner or later issue their own crypto tokens, as Venezuela already is attempting. Due to its extreme volatility, bitcoin can not replace bank tresors. But it is already used in some situations for reducing money transfer costs, since the miners get any transaction rewarded in bitcoin. And above all, anonymity can be a substantial motive to own it. When you need a hacker to delete your drunk driving record, pay her in bitcoin.
