Everyone needs to be careful with crypto influencers, especially noobs. But then again, the golden rule of any investment is Do Your Own Research (DYOR). Anybody is free to invest in any coin and they shouldn't blame the influencers because information on these projects is available online. The influencers are only shilling projects because they're paid to do so by the project Devs. We all need to take responsibility for our actions in theal market rather than whine about influencers misleading folks.
The influencers are just doing their job, to attract naive users to what they are selling to their followers.
It is the responsibility of any investor to do his own homework. As they are spending their own money, you have all the freedom to do what's best for your funds.
