Creating ‘tenant’ tokens residing on the Ethereum blockchain is pretty easy - a developer familiar with the environment can issue a new token every single day.
Having a few decent tokens, the rest of the currently issued tokens on Ethereum blockchain can be viewed in the same way as the ‘toxic assets’ of the housing bubble of 2000s.
Besides, the blockchain can not handle currently quickly enough a large number of transaction requests from all tokens created.
Promises of improvements are made but we are not sure if they are going to be fulfilled.
