Like we've stressed before, the wallet upgrade is very important. If you want to look at it from marketing/price perspective, consider that once BTC2 is in the spot light next, would you rather have it seen as high quality safe coin with all the fundamentals looking good, or as just another temporary pump? Those with not that many coins just waiting for a pump might not care about the long-term use cases and value of BTC2, but we do.
We have the funds for exchange listings, but any new listings will also require volume so even if we got listed today, does not mean that we would be immediately eligible for a top 200 ranking. Not that a ranking is even the only way to gain spotlight again.
Check out how much Ethereum's POS update has been delayed as an example. Delays in crypto development are common. ETA is not a deadline, it was our best guess at the time that we made it. We would refrain from making such guesses if it wasn't for the community asking for them.
Your arguments are good, but that doesn't mean that you are right in everything you said.
Ethereum can afford to make delays, they are already a proven top notch crypto currency, bitcoin 2 is not, and I'm not saying that you can't have delays, because you CAN, we are humans after all, however when you have delays, you give something in return to keep your credibility (and improve it) and the goodwill of the community.
But when you reach an ETA and come empty-handed, that fractures the community and what the people think of you is reflected on the price of the project.
The community is expecting 2 cmc exchanges for a while now, when you reached the ETA at end of the last month, you had to list btc2 in at least 1 of those 2 exchanges to keep the community engaged, (and throw the bad news about the wallet update delay at the same time) that would have kept the community intact.
And yes, ETAs are estimations not deadlines, but we really do everything in life based on estimations in case you didn't know, I mean we are alive today, but we don't know if we are going to be alive next month for example, we are estimating that we will, but we are not really sure because we might get hit by a random bus or something.
