The only thing I don't understand is how your platform benefits from allowing to trade from $100 and such little shares
Actually, that's exactly a new window of opportunity. Micro investors, who are interested to invest just a bit or invest with a spare cash, or simply gamble with a little of money represent an already huge and growing market. Take a look at Acorns, or Stash as examples in classic finance.
Yeah that's a good idea and market opportunity, and might be very profitable for the platform in the coming years, as a lot of young people are becoming increasingly interested in investing in crypto and, well, they usually lack money to do that. Myself included😂
