Security tokens are essentially digitized traditional securities. If you already invest in securities in any form (stocks, bonds, real estate, CDs, etc.) then you are familiar with what it means to hold a security. For example, a security token would simply replace your paper stock certificate with a digital version. When you invest in a security token, you are actually investing in the underlying asset. The fact that there is a security token is somewhat irrelevant — it’s simply your digital proof of ownership in that security. Security tokens are not cryptocurrencies
Pretty much, in the real world if you want to gain something big from stocks, bonds or real estate, you can't be an average Joe.
Hope that helps
If STO's are digitized like you said then it is crypto as crypto is digital. Bitcoin suppose to be the electronic digital version of cash for example. Correct me if im wrong.
