I don't really trust influencers/youtuber right now, they are just being paid to promote some project. It doesn't mean that an influencer is well-known that all of his promotions is legit. I have encountered so many influencers promoted a scam project. Always DYOR and look for a project that are having a development for years or have a legit partnership, in that way we can minimize possible losses or rug pull.
It's true, but influencers also help us get the latest information. then we can believe it or not is our decision, they deliver the news, we do personal analysis and the decision is in our hands.
And from what VoskCoin said, I only agree with Bitcoin and Ethereum
