This is the guide for mining litecoins which is the second most popular alternate coin after bitcoin (and can be mined using GPU). Litecoin can be mined using CPU but it's too slow and you can't compete with other users with big GPU farms. If you have at least a single HD7870 then you be okay with earning little profits.

If you only have CPUs to play with then go with CPU based cryptocurrency like Quark, Secondcoin, Primecoin etc

Yupp, but cgminer will have different parameters. Bitcoin is using SHA256 while Litecoin is using scrypt.

By the way you should be informed that people don't mine bitcoin using CPU & GPU anymore. You'll pay more for electricity than earning back the money on bitcoin, this is because that people are mining bitcoin using specialized hardware aka ASIC miners. ASIC miners can only mine bitcoin and do nothing else, it's very fast compared to CPU & GPU and very expensive too... A decent unit costs around RM15k and the amount of bitcoins you earn diminishes fast from the difficulty hike (too many people compete for bitcoins).

For average joe with CPU & GPU, go for scrypt based cryptocurrency like Litecoin, Dogecoin, etc. If CPU only go for CPU based cryptocurrency like Primecoin, Secondcoin and Quark. These coins can be exchanged to bitcoin anyways.

around 0.0288 bitcoin per litecoin

Not sure, but it can easily to exchanged to bitcoin anyways...

Bitcoin for trading/buying stuffs. My second main coin is Dogecoin which I invest in, third I mine Primecoin on CPU (selling this for bitcoin then I buy Dogecoin using bitcoin). I sometimes trade dogecoin for steam games on reddit. I mine litecoin if there's some problem on dogecoin, for example the blockchain fork that happened few days ago.

No, it means there are two separate ledgers(blockchain) running at the same time, one is the correct one and another is the wrong one. Usually the wrong one is running on the old version of the wallet. To fix the problem just install the new wallet and if you updated on the wrong blockchain, you simply delete the blockchain data on your computer and run the new version of wallet to redownload the correct blockchain.

Yupp, as long as you keep the wallet.dat file or make a backup of the file. This is the private key used to access your coins in the blockchain.

little only, just started for few weeks. I got like around RM180 equivalent like that, but the value is not constant because the price of cryptocurrency always change just like stock market.

If you got US bank account, easy as pie. Just use coinbase and put the usd direct into the US bank account. Malaysia harder, can try use paypal but got case paypal rejects to transfer because got scamming case before (by people not the coins). Or you can try sell directly like cloudstrife07 lol
