For solo mining with a single GTX 680, which will produce 120 Mhashes/s, you would expect to find one block approximately every 98 years. At the current difficulty, solo mining is inadvisable under practically all circumstances. Pooled mining should be done instead. Furthermore, mining utilizing graphics cards is rapidly losing viability with the release of FPGA and ASIC-based mining hardware, which operates at far greater efficiency.

Unless you have exceptionally cheap electricity or have a use for the heat output from the graphics card(s) (e.g. Heating your house for winter), graphics card mining is unlikely to be profitable for you. Additionally, mining with NVIDIA graphics cards has pretty much never been worthwhile, as they are far slower and less efficient than comparable ATI/AMD hardware, conflating the above issues with graphics card mining.

How does it make sense to recommend buying mining hardware, when the whole argument against mining was based on profitability? Assuming you have to 'invest' a lot more than $1000 in hardware for this to make any real difference, when exactly do you think you will break even? Even if you would earn 0.50ct/day continuously - you'll need over 5 years (!) before you make ANY profit. Better recommendation might be to take that $1000 and buy your bitcoins straight out. It'll give you at least 2 right now - technically - they may be worth a lot more in 5 years. – May 2 '16 at 9:31.

I've added a new way to protect against a rollback due to a 51% attack. The database files are updated automatically see post above. If a rollback occurs you can download the database files to regain your information.

For those that are not aware, a rollback occurs when a 51% attack causes the block chain to go back to a previous date. All coins mined or transmitted after the rollback, their records will no longer exist. To combat this, we now have a backup of the block chain on the website, so you can download it, install it and run your wallet.

A 51% attack occurs when one user has more than 51% of the has power and controls the network. In practice It usually requires 75% to be successful. One way to combat this attack is never restart your wallet.The next important way is to use your hash power to mine this coin. As long as there are honest miners, and honest wallets on the network the chances for attackers to prevail is lessened.

PAC: $0.00 + 42.9%: 21.7: PacCoin: LIZA: E0.00056229. Block time: Dev language: Type. Yo how long does TEKcoin take to send? Marcoyuki L3. Its name alone kind of even implies it to be an enhanced fork of PAC and really gives the impression that PAC is/or could be an outdated ancestor by comparison. Based on the growth and new features in the new coin the name would boost way more appeal in news and social media and could go over way better than a seemingly less.
