Blogger and celebrities are been paid when they are used to promote a token/coin. That means they are doing their jobs. Have once fallen into a scam because it's being promoted by a celebrity, although it isn't a crypto scam. So since then I never believe any blogger nor celebrity to invest. I will rather make my own research to invest.
Those bloggers who are celebrities need to take responsibility if they are not mentioning that this is a sponsored video. In most cases these so called influencers promote the project in such a way that their followers think they are also investing in it. Those influencers also mentioned in their project that they are thinking about holding those projects for the long term when they haven't made any investment in them. Everybody doesn't have the knowledge to invest in crypto project so they follow some influencers they like so if those influencers giving financial suggestion to their community then they should have take the responsibility as well.
That is why one should me mindful of whoever he/she follows online. You can never see me following anyone online no matter how popular you are. Any mistake I made base on what they promote, never count on them. Why will I be losing while they are making money.
We also have to understand that people have different mindsets, and everybody is not willing to take on the responsibility of failure. So if the trade goes bad they simply accuse the influencers but if they make a profit from it they take credit for themselves by saying they made the right choice in time. This two-faced people are the ones who are most affected by these influencers. Influencers fasten our information-gathering ability but we should take our own decisions.
