First of all sorry for your unfortunate loss and I wish you have learned from this accident, those kinds of scam are quite common nowadays. It's not only shown on youtube but other social media as well and sometimes google ads show the same, before putting your money in any crypto services it'll be wise if you use the logic and your own diligence. However, since you are a newbie then at least ask your friends/community who have more knowledge in the space.
But isnt it too much to ask from newcomers to a crypto to be able to cope with elaborate scam that involves youtube hijacking , (let me remind when you watch youtube you are in a mood to learn , have fun), ~snip~
There is nothing wrong with that kind of thought. The thing is youtube is not a platform that focusing to learn any particular subject nor to entertain ourselves only but this is a worldwide video sharing platform, there are lots kind of videos uploaded every day includes videos that lead to scam one. So you need to put extra awareness if you watching videos that involve financial stuff.
