there's no need to be concerned. ultimately, the bitcoin supply is getting more and more distributed over time as early adopters cash out and distribute their coins into many more hands. as long as price keeps rising, this process will continue.
According to
BlockChain24.co, over the past nine months, the crypto whales have bought 450,000 BTC. You think is it any danger in whales holding so significant amount of Bitcoins?
i would take those stats with a bucket of salt. they can't possibly gauge OTC trading or deduce from exchange APIs how many coins are going into the hands of "whales".
let's assume the stats are true for a moment. how many of those 450,000 BTC were
sold by whales? whales accumulate
and distribute, just like the rest of us.
