I can see that some people have a high rank and some are lower, is it advisable to take advice from high rank members more serious than jr member and full members?
The more older and higher rank means the person has great experience and he/she is in Blockchain world for long time. So a higher rank member can give a value able and good advice.
A lower rank can give a good advice too. But he/she should have much knowledge and experience in this field.
