You also need to be very careful in the world of cryptocurrencies, because there is a lot of money in this area, and it is easy for attackers to get hold of the weirdos with coins if they pretend to be an honest service. For example, today I received an email from Roobet, but in fact it was criminals, because the email was poorly formatted and when I looked at the sender's address, it was not Roobet support or info, but some kind of gibberish of symbols. I also received emails from pseudo Ledger and Electroneum support. I didn't understand what kind of Electronic wallet it is if I've never heard of such a wallet, and it sounds like a Scam that disguises itself as a well-known wallet.
people are not really prepared about all this thing and they feel it is not i important until they become the victim and this is why they tell every newcomer to be prepared about investing in bitcoin because they are taking a lot of things for granted and they should know that when you are not well prepared then the knowledge you did not take seriously will not be able to save you and this were before you start ask questions most people don't even care all they want is for them to buy and the next thing should be that they should start making profit and it does not work that way and from the way things are done it most be followed.
and that is why you do research and then ask a lot of question to get clarification on things that are not understood because that is the problem a lot of people are getting they need to do better know tools they need before investing.
