I just read an article about the difference between STO and IPO here https://medium.com/@Comistar/security-token-offerings-sto-vs-initial-public-offerings-ipo-6a8885ee721a
Its written there that STO has lower costs and complexity, programmable set up, and more simple for global investment.
I don't know whether this article is concrete or not but it gives me insight. Whats your opinion about this article?
