The cryptocurrency price-tracking website, CoinMarketCap, has confirmed it was recently the victim of a large hack, which resulted in the leak of over 3.1 million email addresses (3,117,548 to be precise). Currently, the identity of the attackers is unknown. In a press release, CoinMarketCap stated:

“CoinMarketCap has become aware that batches of data have shown up online purporting to be a list of user accounts. While the data lists we have seen are only email addresses (no passwords), we have found a correlation with our subscriber base.”

While the fact that passwords were not included in the leak will be a relief to users, the hack nonetheless constitutes yet another large-scale data leak — of the sort which nowadays seem a weekly occurrence. Interestingly, CoinMarketCap has stated that the leak did not come from their own servers — which had users demanding to know where else such data was being stored.

Several other cryptocurrencies have been the victims of similar hacks recently, among them Celsius, Ledger, and BitMEXBinance, the crypto-exchange which owns CoinMarketCap, was also targeted by an attack in 2019 which resulted in 2% of the company’s Bitcoin holdings being stolen.

As the influence of the internet rises, so does the prevalence of online scams. There are fraudsters making all kinds of claims to trap victims online - from fake investment opportunities to online stores - and the internet allows them to operate from any part of the world with anonymity. The ability to spot online scams is an important skill to have as the virtual world is increasingly becoming a part of every facet of our lives. The below tips will help you identify the signs which can indicate that a website could be a scam. Common Sense: Too Good To Be True When looking for goods online, a great deal can be very enticing. A Gucci bag or a new iPhone for half the price? Who wouldn’t want to grab such a deal? Scammers know this too and try to take advantage of the fact. If an online deal looks too good to be true, think twice and double-check things. The easiest way to do this is to simply check out the same product at competing websites (that you trust). If the difference in prices is huge, it might be better to double-check the rest of the website. Check Out the Social Media Links Social media is a core part of ecommerce businesses these days and consumers often expect online shops to have a social media presence. Scammers know this and often insert logos of social media sites on their websites. Scratching beneath the surface often reveals this fu

If you think you have been scammed, the first port of call when having an issue is to simply ask for a refund. This is the first and easiest step to determine whether you are dealing with a genuine company or scammers. Sadly, getting your money back from a scammer is not as simple as just asking.  If you are indeed dealing with scammers, the procedure (and chance) of getting your money back varies depending on the payment method you used. PayPal Debit card/Credit card Bank transfer Wire transfer Google Pay Bitcoin PayPal If you used PayPal, you have a strong chance of getting your money back if you were scammed. On their website, you can file a dispute within 180 calendar days of your purchase. Conditions to file a dispute: The simplest situation is that you ordered from an online store and it has not arrived. In this case this is what PayPal states: "If your order never shows up and the seller can't provide proof of shipment or delivery, you'll get a full refund. It's that simple." The scammer has sent you a completely different item. For example, you ordered a PlayStation 4, but instead received only a Playstation controller.  The condition of the item was misrepresented on the product page. This could be the
