The slow and steady wins the race is what they say in proverb, and Ehealth is doing the same.. waiting ..
Yes, at the moment just wait and see in which direction the cryptoworld will go in the next months seems to be not the worst strategy. At least much better than doing an ICO and EHF is right to do it only sometime in 2019.
I think the current market situation should benefit the projects like EHF for the fact that it has a longer term ICO and its development should coincide in the next bull run probably by next year.
