I don't know the exact percentage, but most of BTC is owned by a few.
So logically, BTC can never become a store of wealth for the masses.
BUT if BTC cannot serve as storage of wealth for all and neither as day to day currency due to very slow and increasingly expensive transfers, what role will BTC play in the future?
I honestly think that it will become a billionaire's toy in the future and coins like XLM which offer incredibly fast and inexpensive transfers, will play the major role in the financial day to day transactions.
So I believe that the people who have just started to invest in crypto should consider these other coins and forget about bitcoin.
If the world will accept crypto as currency, it won't be BTC.
You know, I am a newbie and I also do not know much about bitcoin. I am also thinking about the decentralization of Bitcoin. If rich people and companies are buying thousands of it. Won't they be able to manipulate the market as well? I am not sure about this but I really want to know. Also, when Stock market is down, seems that bitcoin follows.
They can manipulate the market, but they can not always do that because the other company and the whales will not let them do that many times. There will be a time for the bitcoin market will still up while the stock market is down, and the investor will use bitcoin to invest their money. But people can still make money from bitcoin, especially if they can use the moment to buy and sell bitcoin, and we already see it happen many times.
