I always browse Youtube every single day and I always see different Youtube channels being used to scam ignorant investors. I've also seen some popular vloggers here in our country being hacked because of these people and their channel has been used to scam people. They are changing the name of the channel, putting their previous videos into private and make a live video in Youtube.
Right now, Bitcoin is moving higher every single day and scammers are trying their best too to scam people. Just be knowledgeable enough which are scam projects and which are not and you will not get scammed by this hackers who are doing the exact same thing every now and then.
