thereby disregarding hard evidence from the Dash blockchain itself, that very clearly shows the opposite (that the Dash coin wealth distribution is highly decentralized).
He already pointed out to you that that's irrelevant because distributed wallets don't mean distributed owners.
It's particularly poignant with Dash because large holders HAVE TO split their holdings into distinct addresses if they want to run masternodes.
Large Dash holders having to split their holding is irrelevant to Dash decentralized wealth distribution. They could all be sitting outside the top 10, top 100, top 1000 addresses. It does not change
the decentralized nature of Dash wealth distribution.
Dash wealth distribution has a relatively low percentage concentrated in the top 10, top 100, top 1000 addresses and very large percentage concentrated in addresses outside of all that (68,2%).
Litecoin wealth distribution has a much larger percentage concentrated in the top 10, top 100, top 1000 addresses and a much lower percentage concentrated in addresses outside of all that (34,7%).
