The Bitcoin Difficulty has just gone to 2,621,404,453 up from 2,193,847,870 or with other words we have an increase of 19.49%. It is interesting to note that the increase of difficulty this time is the lowest in terms of percentage than the increase of the previous five times. So less than 200% is not bad at all for the moment, giving us some more time before the Terahash ASICs start appearing on the market and the difficulty starting to grow at a much higher pace. Luckily we’ll probably have another difficulty increase before users start receiving their pre-ordered THS ASIC devices and we are probably looking at another 20-25% for the next difficulty increase.

The first Dualminer USB ASIC devices that can simultaneously mine Litecoins (LTC) and Bitcoins (BTC) and alternative crypto currencies based on scrypt and SHA-256 that we’ve already mentioned here have started appearing on eBay. These devices based on a single Gridchip GC3355 processor chip from Gridseed are rated as capable of: 500MH/s SHA-256 and 40KH/s Scrypt when operating for mining both, or 1.6GH/s when mining only BTC or 70KH/s when mining only LTC. Again, price wise these are not very interesting products, unless you want to be able to try the Gridseed chips and see how well they can perform. What would be more interesting are multiple-chip devices that offer significantly higher performance, but the good thing is that things are finally happening for Gridseed and we are actually seeing devices based on their innovative dual mining SHA-256 and Scrypt at the same time Gridchip GC3355 chips.

gyft-electronic-gift-cards-bitcoin

Gyft is an interesting online service for purchasing gift cards for leading online retailers such as Amazon, Gamestop, Facebook, JCPenny, Nike, Old Navy, Sears, Staples, Target, Victoria’s Secret and many others that accepts Bitcoins as well as other typical payments methods. This allows you to actually shop with Bitcoins in stores that normally do not accept crypto currency payments directly, by first obtaining a gift card for a given amount that you pay for with Bitcoins. Of course you can also send the gift card to someone else in the form of a gift that the receiver can use in the specific store and you can pay with crypto without first having to go through an exchange to turn the Bitcoins in USD for example.
