STOs will be a great addition to the crypto ecosystems when eventually there are better framework for the implementation.They will offer a huge doorway for companies to tokenize their assets and make it much more accessible to the general public, that will improve the image of cryptos (as well as market capitalization)in general.Some platforms like Tezos hold a lot of promise in this regard. The down side may be that there may be too much legislations regarding STOs.
