Does your multi millionaire trader friend actually know anything about BrainChip other than what can be deduced from a chart or the most recent published financials? Are they aware of what lies behind all the NDA's? What do they suggest you invest in atm or is it all just short term swing trades? This is not meant as an attack on you or them. Trading, investing, shorting.....are all legitimate ways of interacting with the market, but not everyone has either the stomach or the ethical proclivity to engage in all three.
And a good thing too as the difference means every seller can find a buyer, and vice versa, according to individual circumstance, inclination, luck and persistence. Did your trader friend make a motza on BRN in January '22 when the Mercedes news dropped out of the blue?
