reasons i invested:
solid, stable and old blockchain
no premine, no ICO
fairly launched
the coin's code and idea (short duration POW, POS 3.0) is used later in some other coins after BLK
POS only (energy efficient)
first POS 3.0
Thank you! Now that you are saying, I have to admit I should take its fair launch into account too. I think, this coin has a good and clean reputation, which is rare among alt coins.
But does this technology have a prominent future compared to others such as POW? Because to me, it seems for the major mining organizations getting energy cost-efficiently is not that big issue and people have these doubts about centralization time and time again related POS coins. Does BLK have the answers for these questions?
