The debate will continue, each organization or company claiming their superiority only for their propaganda. In fact, it is never possible to get an accurate estimate of who is holding the most bitcoin. That 's all the rumor.
yeah because people enters crypto investments for their own security and privacy so why here when you will broadcast your investment?
then better stay in banks when your account can be opened at anytime by governments or other bank employee (privately of course).
so basically those Data cannot be accurate and will never be,we are still in speculation and estimation but aside from that nothing is concrete.
