Interesting list but a bit confusing. Top 5 based on what? And how does #4 belong here...? Putting test account along with people who have big input is confusing.
I am just mentioning bitcointalk accounts which will be spoken for decades. Bitcointalk is a top forum among crypto users, in such a forum many people would think upon which is the first account registered on this forum and which might be the first post made on this forum. Today there are tons and tons of new users creating an account each day but the first account created in this forum is worth mentioning. Hardly today only one account is active and has been updating this forum which is theymos for sure whereas most of the users forgot these big names who shaped the bitcointalk. Moreover I have minimized this list to 5 so that it won't create controversy among users. If it was top 10 I would have mentioned some worthy names there and it would have been even more interesting.
