Whatsoever action this may be, i know that it cant be a threat to the market demand or supply, the price may fluctuate to an extent as always been volatile, but the end result will also be in favour of some buying or selling depending on how the market reacts, lastly, this does not also render the market to being centralized, we are not seeing it for the first time, that the whales are moving their asset after a long time into another wallet.
Alot of time rumours like this has always surfaced and claim to threatening the decentralised nature of Bitcoin but every time Bitcoin doesn't get centralised.
I have always try to start in crypto-currency avoiding FUD and FOMO because this is part of the reason people make the worst decision under panic mode.
