why a so low number of voting ?
Most investors are not interested in any developmental activity, all they want is to make money from an increasing price. They have no idea about this voting process.
How many tokens are on exchanges? If they dont vote, this might be a serious Problem. Cant imagine that more than 5 % of all tokens are held by people that know about this voting process [probably less, unless we include block one], and many of them dont know how to vote. So, unless block one and big exchanges vote, 15% might be a far to high threshold.. IMO, voting is the biggest weakness in all DPOS Systems, most "Investors" are just speculators, and cant be bothered with active participation. Even most well known bluechip Stocks probably rarely ever reach 15% turnout..
You know, in crypto there are already fully functional projects , so a new coin must present effective improvements to succeed. ..
