This is going a bit off-topic, so If you want to discuss further I suggest a separate thread, but the weight on ZECs value you are seeing is due to the extremely high rate of issuance of new coins (inflation is at 42%) not due to selling pressure from the ECC or Foundation. The market has to absorb $500,000 worth of new ZEC every day. This will drop to 13% after the halving next year.
I don’t think the continued development funding conversation should be influenced by market value whatsoever. It’s literally impossible to predict.
