Series of tokens have been developed and some are still in the ICO. Those that have been completed and listed on exchange are really suffering a big blow in term of loss of value in the exchanges. The new ones are scared of being listed on exchange at the moment because of the market situations at the moment and the effects it could possibly have on their tokens' value.
Yes unfortunately it happens today, but it seems to me that the team of the project is not interested what happens by investors tokens, they received an ethereum in the form of investments and they have money for the further development of the project if it was originally planned. And they kept their obligations by paying tokens to investors and placing them on exchanges. What will happen next they do not care.
