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.
The rules of the bitcoin protocol include the requirement that a user cannot send the same bitcoin more than once and a user cannot send bitcoin from an address for which they do not possess the private key. If a user tries to create a transaction that breaks the rules of the bitcoin protocol, it will automatically be rejected by the rest of the bitcoin network.

Notice that Craig Wright has made it clear that he is willing to “sacrifice” and even if it will cost him money, he shall channel everything they got to see BCHSV go live. That means, in the run-up, uncertainty reigns. As such capital could flow out of BCH further exerting pressure on the coin. In that case, depending on the exchange, traders should hold off trading aware that losses below $400 shall inevitably ignite sellers aiming at $300 or BCH all time lows.
If you have a brokerage account, you can expect the bitcoin user experience to be similar. And, as with a brokerage account, you’re likely to pay transaction fees whenever you buy or sell. That means day-trading bitcoin probably isn’t a great strategy — since those transaction fees could quickly eat up any profits. If you’re using bitcoin instead of PayPal, Venmo, etc., check first to see if the seller will charge you a fee for paying in bitcoin.
The latest debates around bitcoin’s technology have been concerned with this central problem of scaling and increasing the speed of the transaction verification process. There are two major solutions to this problem, either to make the amount of data that need to be verified in each block smaller, making transactions faster and cheaper or to make the blocks of data bigger, so that more information can be processed at one time.  
As a result, a compromise protocol called SegWit2x was developed. Launching this protocol meant storing some of the information outside of the Blockchain as well as increasing the block size limit to two MB. The protocol was implemented on Aug. 1, 2017, after 95 percent of miners voted for the proposal. However, the network didn’t see the immediate increase in the block size limit. To a lot of people, this meant postponing a problem instead of solving it.
CEX.io is another great option to buy bitcoin with credit card or debit card. They have been in business since 2013 and are based in London, UK. The exchange brings strong security, great liquidity, and cross-platform trading via their website, mobile app, and API solutions. According to the website, they have over 2 million active traders. CEX.io also allows margin trading for those that want to, and near 100% uptime.

Bitcoin Cash differs from Bitcoin Classic in that it increases the block size from 1 MB to 8 MB. It also removes Segregated Witness (SegWit), a proposed code adjustment designed to free up block space by removing certain parts of the transaction. The goal of Bitcoin Cash is to increase the number of transactions that can be processed, and supporters hope that this change will allow Bitcoin Cash to compete with the volume of transactions that PayPal and Visa can handle by increasing the size of blocks.
Ver has put his weight behind the new software upgrade, or the current Bitcoin Cash. But Wright — the Australian computing genius who has on a number of occasions claimed to be Satoshi Nakamoto, the pseudonym given to the creator of bitcoin — argues the software should deviate toward the original bitcoin, hence Satoshi’s Vision (SV), by raising the maximum block size to 128MB from 32MB.

That doesn't mean it's risk-free, though. Blockchain technology is an intriguing development that could disrupt a number of huge industries, but at the moment, it's also a fashionable word to throw around. Long Island Iced Tea, a beverage company, renamed itself Long Blockchain in late 2017, seemingly knowing that the word itself could cause a jump in stock. And for a brief moment, the stock actually did jump just because of that. Don't fall for tricks like that, stay vigilant and avoid cryptocurrency scams like these.
