I don't know the exact percentage, but most of BTC is owned by a few.
Just like in any other investment domain, the rich own the majority. They will always have an advantage in the game: as long as you have the resources, you can have the best advice and take the best step in the domain you're willing to invest.
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.
Other coins are faster but have other features they sacrifice, such as decentralization and security. Bitcoin will likely serve as a store of value for the rich, just like gold is today.
the majority of people don't have the extra wealth to store it through bitcoin. Most people do not own gold and neither will they own bitcoin.
But everybody buys and sells.
So again, bitcoin will not disappear, but it will not play an important role in one's personal life for most of us.But if you can buy your groceries with crypto this is important.
So IMHO, if we pick the right coins today, which will become currency tomorrow, this is the last chance to make a fortune.
In a few years, once these coins are established currency, it will be too late to make 100+ gains.
Here's the fun part: 1g of gold is quite expensive for the average person to invest in.. especially when you know that the less grams you purchase, the more it costs per gram. On the other hand, the smallest amount of BTC you can own is $0.000547. You don't need to spend $54.7k on a BTC to own it. You can own as much as you want, starting from the 100 millionth part of a Bitcoin.
If the consensus ever changes and more decimals are added, you will be able to own even more. Lots of people have the wrong idea that you have to purchase an entire coin.
You don't.
So again, bitcoin will not disappear, but it will not play an important role in one's personal life for most of us.But if you can buy your groceries with crypto this is important.
Decentralized assets will never become an important role in our personal lives. Governments won't allow that to happen because they can't control these assets. Hence, what you're looking for is CBDCs. But they're gonna be centralized, the government will inflate them exactly like they do it today with fiat and your wealth will never grow. In fact, exactly the opposite will happen: your wealth will be reduced every single year by the annual inflation rate.
So IMHO, if we pick the right coins today, which will become currency tomorrow, this is the last chance to make a fortune.
In a few years, once these coins are established currency, it will be too late to make 100+ gains.
It's not the last chance - you're still an early bird. We all still are early birds, since the blockchain technology has only existed for a little over a decade so far. It's like the humanity only discovered gold 12 years ago.
Centralized coins are going to be fast, cheap and so on - but they will never let you grow financially. So those "100+ gains" will only turn out to be a dream. If you want to sustain the actual system, I honestly think investing in fiat is much better than investing in centralized currencies at this point.. especially considering what XRP has gone through recently.
Bitcoin will stay as the king of cryptocurrencies, and nothing will change that. Many other altcoins are just testing grounds for new Bitcoin tech and features.
