What you are saying makes sense and it definitely shows interest in crypto. I just don't understand why Goldman and Sachs keep sending mixed signals to the market, making it hard to understand if they support crypto or not. Anyway, unless Poloniex changes to much, this should provide a way for institutional investors to come into the markets, because Circle definitely has the means to legitimize crypto trading, now that they are the owners of polo.
They certainly support it. Right now they are just dip dapping their tippy toes into the crypto water.
Security tokens will bring investor protection with them which will really open the gates to huge financial investments, especially from Goldman and Sachs etc.
Right now there is no investor protection, if the coin or the project dies, you are fried. This will not be the case with security tokens.
