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.
Those influencer are just our guidelines and its our job to validate their statement and know if they are indeed telling the truth about the projects. In a volatile market there’s no such safe investment because anything can happen even Bitcoin we can’t say that its a safest coin to bitcoin. The market tells the price movement, knowing when to buy and sell is a great strategy we can have.
