yes, greatly influenced my decision to buy the altcoin. because if you get the top holder owning more than 50% then you have to stop and take the decision to ignore the altcoin so you don't lose assets in the future. try to learn about good altcoins then you won't find the top holders own more than 50% . so if you want to buy an altcoin then look at the top holders owning as much as 10-20% only.
