no one can stop whales from dumping especially if the price is really too high. For me the best things to do on it is to ride what they're doing, i mean when you see a strong uptrend buy if you're not late then when you see a small fluctuation always execute your take profit strategy, then wait for confirmation to buy again if it will continue to rise, if not then don't ever place another order from it because surely it will make more correction.. Whales always make hype when they see it's crowded but if not, expect there will be a massive correction that can lead you to a massive losses as well. So be smart because no one can really predict when whales gonna manipulate the market it's very unpredictable to be honest..

You can't do anything about it. Probably 1000 people own most of the world wealth too so It is not surprising that something similar is happening with btc. That's called capitalism. And the opposite where everybody shares everything would be communism. If everybody had the same amount of money, either everybody would have Ferrari's or nobody would have any cars. Some people must be poor so some others can be rich. That's how it works.

there is nothing you or anyone else can do, the rich are free to spend their millions of dollars buying bitcoin, if you look you will notice that it has even become fashionable for some people or companies to display that they hold many bitcoins, this has become a competition for the rich . the concern would be:

on the day that those who have so many bitcoins start selling how will it be?

maybe they sell in a way that doesn't hurt the price, maybe

but still worrying that a small group holds too many bitcoins

I don't know why people expect to be very rich by doing nothing. Those 1000 people holding a huge amount of risk by holding bitcoin. Whether they bought when bitcoin was under a dollar or 1000 usd, it doesn't matter. If btc goes down by 99% tomorrow, they are all fucked. Right now they are rich as fuck because they are getting rewarded for the risk they are carrying.

We couldnt really tell but this is way more better than with traditional assets or stocks on where they could really somewhat make it as some sort of monopoly or they could really control it most of the time but its true that with this market then it is somewhat not really that possible
even though they could really still make some impact but not really that much of a concern even you are just a small fry you could still able
to ride with the waves and take advantage with these movements.

You cannot make your comparison with whales and still if they hold major portion of bitcoins in circulation at this time the btc still remains decentralised as you cannot make it like other altcoins in the market.With increase in prices the and and supply being limited the whales will be able to acquire less and less even at high paying budgets also.The best you can do is to make investment on your basis and what you can do and rest leave this as nobody is going to stop investing and there are only 21 million of them available.

First you need to be clear that bitcoin is not centralized. Bitcoin is only crypto currency which is decentralized in true sense. Also it does not matter if 40% of the bitcoins are owned by 1000 individuals. They won't dump them together and even if few of them did, there are too many people who will be willing to buy cheap and hence don't expect the price of bitcoin to fall too much.

You should pick a better term since people usually mean "centralization of the network" when they speak of Bitcoin centralization.
Not agree! Just because some people have more Bitcoins than others does not mean the centralization of the market.

Whales are inevitable. There will be whales at any time, and we cannot do anything to them. When the price of Bitcoin gets higher and higher, we will also consider whether we still choose to sell Bitcoin or continue to hold Bitcoin. But most people will continue to insist on holding Bitcoin. We can only manage ourselves. Don't do unnecessary research.
