Except it's a mentor whom you know one on one or you have a personal relationship with the person, that's when you can trust the person but if they referred you to anything, as a wise person, you should also do your findings about the platform they referred you to. There was this traditing platform that was promoted last year by so many online influencers who posed as good traders but the platform they promot never had a good review when I did some research about it, but yet there are some people that will fall victim because they got the referral from someone they trusted.
And this is why we should not blindly trust anyone, we often trust someone we know and participate in platforms they refer, but it is important to keep in mind that trust and verification are two different things. You should always do your own research, verify, especially online matters, nowadays there is no shortage of scams in the promotion of any online matter, so blindly trusting them is dangerous, so you should always research well yourself and then make a decision, because only you will have to bear the burden of the loss, so you should make a decision based on your own personal research on any matter.
