These are interesting numbers but I think you're a little off on your conclusions. Firstly, if you're going to add in the liquid Hive these accounts have then you have to add in the liquid supply as well. You can't say the total HP is 160M and then add in liquid Hive to the HP. If you just add the HP then the total is 23.4%, not "almost 30%". In fact, it's less than 25%.
If you use your number of 400M total Hive, then the liquid Hive they hold is @5.4M of @240M liquid or 2.25%.
I'm just pointing out that the numbers aren't quite as extreme as you're painting them.
HP is the governance token of Hive and these 4, while large, don't even come close to the 50%+ needed to make changes to the blockchain. With 20 witnesses, there is still plenty of HP available to outvote anyone trying to make proposals hurtful to the blockchain. Factor in that blocktrades is one of the driving forces in the development on Hive and you could see their large stake as being a positive rather than a potential negative. I'm not familiar with what the others do but they are also probably pushing development behind the scenes as well.
Thanks for taking the time to put this together. It is important to stay aware of what is going on with the token supply. I just wanted to point out that the numbers, while substantial, are not quite as big as you are portraying them.
thanks for pointing this out. I included it with liquid Hive because they could convert their massive holdings with one click into HP. But true, it complicates things. I think my point actually is still very clear: Even taken only the HP, 4 people would still own around a quarter of total HP. It doesn't matter to me very much if it's a bit less than 30% or 23% - it shouldn't be anywhere close to these levels. It should be perhaps at around 1% or so... even 4% could be somewhat acceptable.
It's a huge deal if the concentration of a coin/token is so concentrated. Luckily for us, the people outlined here do not seem to dump Hive on the markets (with blocktrades being a core dev of course). More on this tomorrow.
