If the person is reliable and has proven his skill through choosing a good coin, then we might give him a vouch.
But depending your decision on others opinion isn't enough to see that you are growing in the market. It's not about enjoying of following someone's post/suggestion.
It's about on how you are absorbing his good ideas and you are gaining knowledge while learning with his words.
That's why when you search for something reliable source of information is needed, you may trust some people some are not but the thing is that you need to analyze also what information are you going to take and to believe. Don't believe all that you read think and analyze it also.
