1. NFT, non-homogenized token, is a type of data unit on a digital ledger known as a blockchain, where each token can represent a unique digital profile that serves as an electronic authentication or certificate of ownership of a virtual good. Due to their non-fungible nature, non-homogenised tokens can represent digital assets such as paintings, artworks, sounds, videos, items in games or other forms of creative works. (1) Common NFT scam methods (1) Buying a pirated NFT collection When buying, you need to confirm that the NFT is from the correct collection item, which can be judged by the item's blue tick certification, number of issues, etc. ②Fake NFT websites If you are interested in investing in NFTs, you first need to find a place where you can buy and sell NFTs. When you search for trading sites on the internet, thousands of search results will appear on the webpage, but many of them are fake NFT trading sites. Sometimes it can be difficult to tell the difference between a scam site and a real one, as scammers are now making fake sites look like the real thing. There are no real or valuable NFTs on the scam sites, so if you buy NFTs on them you're just wasting your money. Worse still, scammers can record all the information you enter on the site. Usually you only need to provide the MetaMask wallet address to trade, but a scammer may ask you for your ethereum wallet helper (the master key to your cryptocurrency wallet) and use the information you provide to hack your wallet and steal all your crypto assets. Choose a legitimate NFT trading site The easiest way to stay safe is to choose a legitimate NFT trading site. There are many different types of NFT, sports, video games, virtual real estate and more. In addition to the best known NFT trading platform, OpenSea, a number of other legitimate NFT marketplaces/NFT collecting sites are listed below. Art NFT: Super Rare, Foundation, Nifty Gateway, Rarible, Zora, Mintable. Sports NFT: NBA Top Shot, Sorare. Gaming NFT: Axie Infinity, Street Fighter, Myth. Virtual Real Estate NFT: Decentraland. Twitter posting NFT: Valuables. ③Trading in different cryptocurrencies As a result of trading on the same exchange many times, people may get too used to trading in the same cryptocurrency (e.g. Ether on Opensea) and lose sight of the importance of the type of currency. Someone may see such an opportunity to quote in cryptocurrencies that look similar but have much different values, and may accidentally sell the item at a very low price. ④ Inexplicable private messages and winning messages However, it is not uncommon to receive personal messages from the NFT team or the developer of the project you are currently following, telling you that you have won a prize or that the NFT project you are following has started selling in advance. Remember, don't click on the link when you receive such a message, the biggest no-no is to link your wallet to the website they provide! Almost 99% of development teams state that they will not contact individuals privately to avoid people pretending to be them, and if they do have information, most of it can be found on official communities or forums. Runaway scams A runner scam is when a person or group of people initially release a set of NFT collectibles as a way to start a larger project that is planned to unfold over time by way of game components, merchandise or events. They then run off with the millions of dollars they have raised without completing any of the actions they have promised to do, such is a runaway scam. In many cases, the scam will happen overnight, but there are other times when it's a slow and steady process and you'll find the project gradually abandoned, no longer updated and little new progress made. The best way to avoid getting caught in a runaway scam is to do your research. Research the team behind the project and assess their long-term business plans. Follow the project on Twitter, Discord or other public forums, as NFT projects should have a fairly active community of investors if they are to have good liquidity or lasting artistic value. (6) NFT portfolio packs mixed with counterfeits When you want to buy more than two NFTs on Opensea, you may think of buying more than one NFT at a time in a bundle to save on the large amount of Gas fee you will have to spend on each transaction, but be careful, you may have fallen into the trap of someone who wants to save money by using a bundle. A very common combo pack scam is to bundle three or five NFTs into a group and sell them, but when you take the trouble to check, you can easily discover their secret. (7) Buying NFTs at too high a price This can lead to sellers temporarily changing their prices without the website being updated at the same time. Buyers who are in a hurry to buy without careful confirmation may accidentally purchase the item at a high price, for example, if the seller temporarily changes the price by one digit, although the website shows a price of 0.09, they may purchase the item at 0.9 at the time of transaction. (2) How can I prevent NFT from being stolen? ① Install the latest software system and anti-virus software ②After receiving any files or links, scan or upload files to Virus Total with anti-virus software ③Create a password with high security and use double authentication ④Use a cold wallet and verify wallet security settings ⑤If someone steals your NFT, use the DMCA to file a copyright complaint ⑥If you receive a request to create an NFT, first stop and think about it and ask yourself a few questions: is the request coming from an account in good standing or a newly created account, do they have any comments in their avatar.
