Sometimes, as anyone else, I have doubts in HIVE... especially when we have some big drama, or some big account leaves the platform, but then, I remind myself that happens everywhere, not just on HIVE... In general, HIVE has very good foundations and it survived 2 heavy bear markets, development is here (a bit slow, but people are doing stuff), so we still have good chances compared with others...
Because of all that, your comparison with Bitcoin is very much valid! It was ignored, nobody cared, but it just was there, doing block by block...
