I would like to share with you this guide: https://thetokenist.io/security-tokens-explained/

because i think there are some interesting informations on it about security tokens. Here you are a quote from it:

"There are over $256 trillion of real-world assets in the world, after all, and connecting this to consumer investors through blockchain could transform the way we understand financial markets. As such,‘the opportunity for crypto-securities is truly massive, especially with regards to asset classes like real estate and fine art that have historically suffered from limited commerce and liquidity’.

Security tokens could be the next big thing in the Crypto market.
