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.
Oh, yes, that is a really big issue. Those projects who gathered funds in ETH are in big trouble if they did not fix it. Many could just go nowhere, as they will not have enough funds for declared things in the roadmap and that is a big issue. Weak projects will die shortly if they did not have a good financial planning.
On the good side, the projects will learn how not to spend money on not effective marketing, which some really do and they will be more accurate with the funds. Secondly, many projects been greedy by not fixing to fiat, as they thought ETH will raise and thus they will have more funds. Meaning they speculated on the contributors' money, that is quite a lesson for everyone.
