That surprises me. Yes, B&C needs to begin to operate, but the issue of paying for the block explorer is barely related. It will take about 1% of the budget to fund the explorer. We need an explorer so normal people can look up transactions and the results of voting.
I am operating under the presumption current funds will be insufficient to complete the exchange unless they are converted to NSR and NSR goes up quite a bit while they are held. So, paying for the explorer is unlikely to have a material impact on whether the project needs additional funding.
I have heard that exchanges often won’t list an asset that doesn’t have an explorer. It is considered very basic.
Will others comment please? I suspect @Sabreiib is very much in the minority on this question.
