Even now that the price of bitcoin is still below $70,000, there are people who are still unable to afford a whole bitcoin, which is never a problem and shouldn't be a problem.
 
Even if Blackrock and other financial institutions want to buy more bitcoin, the thing will still remain the same. You can only reduce the amount you will buy if the price goes all up, just as those who didn't buy when the price was below $30,000 have cut down their budget.
 
One thing you need to know is that the bitcoin price will always move up above where it is right now, with or without this blackrock purchase.

They are just helping the process speed up a little bit, but the bitcoin price is going to remain stagnant, so if you have money to buy, use the opportunity of seeing it at a low price to accumulate what you can.

It could be all bad and about to get even worse.

The most obvious negative thing about it is the fact that they are buying bitcoin cheap while individuals either ignore bitcoin and will continue ignoring it until it is worth a lot more (like a million bucks) or the individuals don't have enough money to purchase bitcoin now and they'll have to slowly accumulate over time as price keeps rising.

But the less obvious problem could be what they're going to do after they amassed bitcoin... What if some day they started something along the lines of "fractional banking". Like starting to sell bitcoin IOUs to people and sell more than they have. For example if they actually owned 1 million bitcoin but sold 10 million IOUs. What would that do to bitcoin, its price and its future? That is the scary part...
Today they're selling ETF IOUs to people that is supposedly 1:1 but who's to say it's going to remain this way...

Blackrock buying bitcoins is neither good nor bad, but this is reality. No matter how you feel about it, you can't influence the outcome or change it.

You voiced the positive side - this is an increase in the price of bitcoin. The negative point is that too much bitcoins is concentrated in “one hand”, which is clearly not very good. It would be better if bitcoin was more distributed among smaller BTC-holders. If Blackrock (and other big holders) continue to accumulate bitcoin and not sell it, then this will further exacerbate the imbalance in the evenness of bitcoin distribution. Although the uniform distribution of bitcoin between holders looks like a utopia and is no longer possible to bring this to life. Due to the bitcoin concentration among big holders and the high cost of it, a cycle occurs, that is, the more expensive bitcoin, the less bitcoin small holders can afford and the more institutional investors buy bitcoin. It turns out to be a vicious circle in which big players become the dominant holders.

To me, it's neither good nor bad. Bitcoin is decentralized and available to anyone who can afford it and wants to buy it. As a part of a free market, big players can also invest if they feel like it. But, thankfully, at this point Bitcoin is so huge that I don't think there's a single company that can accumulate such a truly significant amount that would allow them to monopolize the market and can significant control over it.
Big funds investing in Bitcoin can both boost its price and reputation. And there's still plenty of BTC left to buy and store in non-custodial wallets. Yes, when the price goes up, it means people can afford smaller amounts of BTC than before. But that's just natural.

Most people will say good because they only care about the price and don't care with privacy.

For me it's bad because Bitcoin will be less decentralized, decentralization isn't only on the hash rate or network, but we also need decentralization on the holders.

Protection in what? I think Bitcoin holders don't need to have a protection from the government because if someone lost their coins, it means there's something wrong with their OPSECs. If you lost your coins in hardware wallet or cold storage due to hack, $5 wrench attack, etc, I don't think the government will refund your coins.

Only popular centralized entities e.g. Mt.Gox and FTX might refund your coins, even though there's no 100% guarantee, deadline or how much they would refund.

I think it's great news if Black Rock buys Bitcoin. I think if they buy bitcoins surely the price of bitcoins will increase, popularity will increase and it will be stronger.

If black rock company buys bitcoins and buys altcoins we do assume the price of all those coins will go up if so I will be very lucky here because I hold another coin besides bitcoin even though it is altcoin. I am sharing a picture here which I collected from a telegram channel. I am marking in red the two coins I bought.

I am sharing the picture here true false you can consider. But the coin I buy and hold after Bitcoin I expect to be very successful with this coin.

Every event will always have advantages and disadvantages. Institutional investors will increase Bitcoin awareness and adoption. They will also contribute to the increase in the price of the currency. Which means more money for long-time holders. Many people would never invest in Bitcoin directly except they use third parties. So it is good news for them since they can now invest through ETF.

The disadvantages will be more centralisation which undermines the ideology of Bitcoin. There will also be more regulations and invasion of privacy. It could also lead to misinformation since people might think that these third parties are the only means of investing in Bitcoin. Some persons use Bitcoin to avoid tax but with this investment platform, avoiding tax might be difficult.

Everything has pros and cons, if they buy a large amount of bitcoin, it will push the price of bitcoin up, but if they sell bitcoin and take profits, it will also cause the market to fluctuate. And what's more important is that there's nothing we can do to stop them, so there's no need to discuss whether them holding a lot of bitcoin is bad or good.

Many people want bitcoin to become popular but they forget that once bitcoin becomes popular, it is inevitable that large funds will jump into the market and buy the majority of bitcoin. As well as governments will get involved and there will be more regulations for bitcoin and the cryptocurrency market. We need to adapt to what comes next because we cannot fight them.

It's always important to understand the importance of accumulating of bitcoins in implying the DCA method. This would help you manage your purchasing conscience in the sense that you can budget a specific amount of money to be Invested and then you watch over the market trends so you gradually accumulated based on the fluctuating potentialities of the markets trends. It can either befalls to favour your purchasing where you can actually buy more or goes against your wills where you'd have no choice than to buy at any amount that the market is currently trending which by any means, you can meet the market when the value is depreciating or appreciating.
But I can tell you that the current market trends is not too high for who's coming in newly to the bicoin industry to buy theirs and hodl in as much we haven't reached to the bull run yet.

While on the DCA method, you can also decide to hold on to your accumulations until halving but you it could be dramatic that while you're waiting for the halving, who just bought at the moment could be lucky to catch up with the further increments they market may offer before the halving.

Blackrock getting into Bitcoin is a HUGE deal. This isnt some small-time play, this is the big leagues. It screams Bitcoin's a major asset, one the top players take seriously. We crypto folks were right all along, and this proves it. Now, this is fantastic news for those already holding Bitcoin. Blackrock doesnt mess around. Their investment tells the world this stuff has real value. BUT, and here's where I feel for the average Joe, it aint all sunshine. Suddenly, getting into Bitcoin gets pricier. Thats the reality of big money.

Some worry this is too much too soon. I hear that. But in this game, timing is everything. Blackrock changes the landscape. My advice? Dont panic. Get educated, get prepared. Remember, OWN those coins, use secure wallets. The future is digital, and Bitcoin's in the driver's seat. The best is yet to come.
