I have nothing against the concept of rich people getting richer, I just was thinking at which way could favour the best distribution and thus the adoption of the coin. It is true that whales would distribute their BTC between many addresses, but as I said, they would not waste their time in creating the THOUSANDS of addresses needed to store one BTC each, even if this could be done with automation (but to create an automate system still needs time and skills), so in the end even if whales distribute their BTC between some addresses they would still end up receiving proportionally less coins than the little holders, which means more coins available for more people.
And I also agree that the distribution also to holders of XRP and ETH and other altcoins would create mothers of all whales, and making the distribution process too complex, while the idea which I've suggested would be very easy to realize.
