@Kiaan I was going through your posts and came to know that you are a very senior member of this forum. More than 5,500 days, 5x than me. Do you think is it possible study the subject you mentioned? Even we can't get correct figures of survey in our forum. So at the national level, who is going to conduct this survey. After survey one can study. Not possible to clear doubts.
In Grey market the deals are managed on faith and not done on open platform and advertised. You know better than me. So, CHALTI KA NAAM GAADI.
Grey is a great tool for investors.
Please don't mind my words.
