Bitcoin Cash itself was created through another acrimonious hard fork last August. That schism was motivated by a disagreement about the size of blocks in bitcoin's blockchain. Most of bitcoin's developers favored retaining the 1 megabyte block-size limit that was in effect at the time (a hack called segregated witness has increased the effective block size since then). The hard limit contributed to severe congestion on the bitcoin network, pushing transaction fees up to a median of $34 in mid-December. Bitcoin Cash supporters created their own version of bitcoin with a much higher 8 megabyte block size limit (later raised to 32 megabytes)—allowing this rival version of bitcoin to process many more transactions per second with negligible transaction fees.
The largest bitcoin exchange in the world at the moment in terms of US$ volume is Bitfinex, although it is mainly aimed at spot traders. Other high-volume exchanges are Coinbase, Bitstamp and Poloniex, but for small amounts, most reputable exchanges should work well. (Note: at time of writing, the surge of interest in bitcoin trading is placing strain on most retail buy and sell operations, so a degree of patience and caution is recommended.)

BCH is a cryptocurrency established as a result of the hard fork that took place to manage the scalability problem. Bitcoin Cash has a number of significant differences to Bitcoin: it is advertised as being faster and cheaper to use, the maximum block size is eight megabytes against one in previous Blockchain, and it has an emergency difficulty adjustment feature. Bitcoin Cash also uses 0-conf (or zero-conf) which allows for nearly instant transactions, meaning Bitcoin Cash transactions are almost always confirmed in the next block.

What these sites usually do is they take money from people around the web and promise to give them good returns. They will then start off by paying these returns through money they get from new sign ups and create a big buzz around the site. Usually they will also have some sort of referral program so that users can bring in their friends. This will go on for around 3-4 months until one day the website will just go offline and the money will be gone. No more payments will be made and a lot of people will get mad that they got scammed.
