Yes I agree. That second spike is way more relevant than the first one. That first spike is quite meaningless as that was when BLK was coming out of it's PoW phase. It was a hike that most alt coins took right after having been formed. BLK had no ICO, no pre-mine or instamine, and yet still that mining phase was a bit too short for my liking (maybe I'm just bitter because I never got to mine it at all, I didn't know BLK existed back then). Still, out of all the PoS coins, BLK enjoyed the fairest distribution of them all.
BLK has been incredibly low for YEARS, not a fun place to be if you like the devs, like the technology while watching other coins steal BLK's thunder. However, that's also when traders who speculate on pure technology alone have a chance to catch up after that PoW phase.
On top of that, PoS coins WILL behave differently when they grow big. If staking starts paying your bills it becomes less interesting to dump on new-comers. What you're selling is your dividend (which is essentially what it is) which is a very stable dispersion of coins to newcomers. PoS biggest strength is that it lacks all the miner shenanigans. Something many crypto-fans have been burned on. The point of entry to participate in the network is incredibly low.
It may also be why BLK genuinely is averse to strong hype. A wide wallet distribution is more important to a PoS coin than to a PoW coin. BLKers want to see stable staking, their point of sale may very well be never.
Just sifting through most peoples photo albums would be such an epic task it'd be too much work for most to bother with an attack.
Yeah, back in 2014, the Cambrian explosion of alts, many people used to store their wallet in their email. There were people who were able to hack and have a script search for the .dat files that most wallets came in and simply 'harvest' them. You didn't need to know whether people held wallets in their email storage, just trawl through all the emails you have access to and sift for gold. You can't do that with jpg files because everyone has jpg files stored in their email. Especially if you don't know how many keys the Blackhalo wallet address is stored with. Doesn't have to be two, it can be more. You could even find them all and then realise that there's another key stored in a different account you aren't aware of.
Blackhalo is a bitch to hack. And one of the wallets could even be sitting on someone's exposed drive, staking. Completely invulnerable because the keys could be manifold and anywhere.
