Thanks everyone who explained their point of view. I do get it - if I invested in something and it dropped in price, I wouldn't be happy either.
By this argument you would be happy if the price drops to 1 sat so whatever block you are holding would be effectively worthless despite the fact that you paid twice as much for them last week as you would today. Last time I looked, the price of something was supposed to reflect the confidence the market has that you will see that return someday. Concern about the price is a concern about this apparent lack of confidence. Therefore if the team is not concerned about a drop in price then they are not concerned about a lack of confidence in their abilities to deliver. I only hold about 2000 blocks so it's not a big deal to me. But personally I would be worried. And also I would be worried about the fact that any future ITO by them (e.g. the one proposed for XC itself) would almost certainly be unsuccessful. These are all just facts, not really subject to opinion.
Emotionally, I probably wouldn't be happy if the price dropped to 1 satoshi after I paid a lot more for it, but from a purely logical point of view, money spent in the past is irrelevant, and the low price would give me the opportunity to purchase more. Understand it would be different if this was an altcoin, whose value is purely determined by its worth in BTC. An altcoin's BTC value is its entire value, period.
BLOCK seems different because its value can be measured in terms of how many NHZ assets you can trade for 1 BLOCK, which from what I can tell is completely independent from BLOCK's BTC value.
NOTE: If I'm wrong here, and the BLOCK/BTC exchange rate determines your BLOCK's NHZ asset buying power, then my entire hypothesis is wrong. Also the price of BLOCK doesn't have any bearing on project development or success, since people are basically just trading ITO receipts at this point; the project is already paid for.
If you are planning to sell BLOCK for BTC, then yes, of course you want its BTC value to increase. But if you want to benefit from the NHZ asset payouts from Blocknet, then the important value is how many NHZ assets you can exchange for 1 BLOCK. From this point of view, my only (rational, selfish) interest in the BTC price is for it to get lower so I can buy more; I'm planning to trade for NHZ assets, not ever to sell it for BTC.
But yes, I do understand the disappointment of BLOCK's BTC price from a purely human point of view, and I also agree that the drop in BLOCK's price could negatively affect the success of any future ITO by the team - that is a really good point.
