#3: Does the website (or company) promise extraordinarily high profits? For example, they can offer that you can double your investment in a week or month. This is a common indication of a scam.
When you see this kind of offer, there is no doubt that it is a classic fraud, it is only a matter of how it is presented and how much effort and time someone put into the whole thing. Forget it, or better report it if you are sure that it is a scam.
#5: Malware has long been a weapon in the arsenal of online scammers, For Example: "Masad Stealer" is using the Telegram app to steal crypto-currency by accessing browser passwords and clipboard information, The attackers access wallets containing Monero, Ether, bitcoin and other forms of crypto-currency
Always pay maximum attention to what you click, but also use the help of security software, this is something that can save you even if you make a mistake. Your smartphone is vulnerable, just like your desktop computer, security is not something to be neglected, on the contrary, we should be at least one or two steps ahead of the hacker if possible.
#8:Try to Use a cold wallet
A “hot” wallet is one that’s connected to the Internet, and a “cold” wallet is one that’s held offline, Storing your crypto offline in a physical cold wallet is usually considered to be a much safer option than using an online wallet, You can use "Trezor"
Note: Please Avoid new and untested platforms.
You put Trezor under quotation marks, so I guess you know this is not a real cold wallet, you still need to connect it to the internet as most people do. Then you can become a victim of fake Trezor sites which will ask you to enter seed words there. Very naive, but sometimes a very effective and inexpensive way of scam.
(more difficult for brand new/masquerading for other companies in other spheres tho, which adds irrelevant info up in research, tbh)
