But in the same moment we'll have another coin, (like people that have BTC and BCH in the same time) that carries on the original idea of PoB and develops it into direction that can help it recover the community and the market price.
I'll emphasise this point until its significance is acknowledged and the issue addressed ...
I find it difficult to see any significant demand for a new Slimcoin chain, which makes the personal ROI very doubtful.
I understand your point, but if I think about BTC it doesn't have any ROI at all, and many other coins as well and in the same time there is no point in seeing the main capital's market value decreasing in order to have some tiny ROI, that any case doesn't compensate the capital's loss.
There are people who are looking for a kind of permanent ROI, but I wouldn't say they are arriving in great quantities here, there are other people that are investing into the coin they believe will increase in its value. Without the later we can't hope the price of SLM will grow. And to have them we need at least to improve the code in order to be it smoothly usable by not technically savvy people. And then, with the help of the PoD token we'll be able to begin thinking about development.
