The buy in mean what, exactly? Before the IPO began...
Ethereum forum was dead and barely had any activity
Videos barely had any views
Barely mentioned on BTT
Periodically only mentioned on Crypto news websites..
Then now during the IPO it hasn't really changed a whole lot. Who exactly are these people who are investing $100K+ amounts as if it was loose change?
But what does the top 100 mean if we don't have access to this information? Maybe it's 10 people who own 40% of Ethereum.
As well wallets =/= unique persons. If you're going to invest millions then you're not going to do it with one wallet. Reasons: Want to avoid the attention that one guy is taking over the whole coin (captain obvious ponzi scheme alarm). Second, you don't want to lose all your coins if you get hacked (having multiple wallets lessens the possibility of losing all your coins to a hacker).
Interesting that on their link it says top 100 Doge wallets own around 45% but I don't think anyone viewed Doge or BTC as a money making opportunity when they first came out.
As well as a distribution where 100 wallets (wallets are not people - I can have 10 wallets if I wanted to) owning half of a coin is terrible end of story. It may very well be 12 people who own half of Ethereum and they could had been Ethereum insiders or supporters from 2013.
