RE:Katya Research article on Vanadium Katusa is a con artist. His article is mostly negative on vanadium and he has dire warnings to use caution while investing in vanadium. He does not mention any names but for a subscription only $3,500 he will give you the names of a few! He doesn't care if he makes money on investing. If he gets just 100 fools to invest in his newsletter he makes 350 grand a year.
