This is good advice because lots of people don't know the difference between a legitimate proposal and a scam, but generally if it sounds too good to be true, that's because it probably is so make sure you stay away from these types of offers
But becauase the channel has a lot of followers they will think this is legitimate and that's the problem even its too good to be true there still people greedy to try it and they will only realise that its scam once the eth send to the provided address.
Although if the channel has a lot of followers, it doesn't mean they are legitimate and look legit because we know that the followers can be bought from the other services. We need to search for the other news about that so we can know if they are telling the truth or not, and we can follow the step to make money.
I highly suspect that this is why Youtube has a case with cryptocurrency and crypto related channels in the past where they deleted all of its content regarding cryptocurrency. Although the scam scheme is true, Youtube considered it and put it back. Seems like the scammers are getting hard time to catch ignorants and keep upgrading their scheme but if you are not new with this industry, you will notice it easily with the "Send first" procedure lol. There are really gullible people especially when they are trusting the website ( Youtube, Facebook etc.)
We need to be careful if we want to follow the giveaways because not all giveaways are true. There is no easy money that we can earn from doing an easy way. All the things we do will need time to earn some money, and we need hard work to earn that money.
Giveaways are true I can assure you that but it does not comes with huge amount since they are not giving it on a single person. Giveaways that are too good to be true is the scam one, it tends to look catchy and interesting at first but when you go deeper to it you'll see how shit it is.
