greyscale own:
blockstream (the bitcoin dev group)

they also own all of these bitcoin exchanges and digital currency services

its more then likely 50% of all bitcoin in the last 4 years that have entered an exchange have touched the hands of greyscale

Exactly what I was going to say. People talk too much about Grayscale, but they are just a custodial service.

Just like Binance, Coinbase, etc.


Not just that.
There are some institutional investors, pension funds, etc can't buy bitcoin directly due to regulations and legislation. But some of those funds are able to buy a Bitcoin Future, or even a Grayscale share.

So, it is not solely for small investors who don't want to hold bitcoins. I believe most of their clients are institutional

Why not add binance coinbase bitfinex and other big custodial services? I would like to know how big step they compared to grayscale

As far as I know Grayscale is not a self-service company and they won't get the bitcoins by themselves. Grayscale is somewhere that people invest and deposit their bitcoins. Just like the exchanges such as Binance and Coinbase or any other exchange. Also, the bitcoin development group named blockstream is owned by them, in the other hand by owning many other exchanges it's completely possible to see the grayscale is rising so much. And surly, rising the grayscale one reason of why bitcoin price is rising so much.

I tend to agree above with my post.

Grayscale is indeed the most trusted custodial service and they act like a bank for Bitcoin holders regardless of whether you are a small or huge investor like whales.  The important thing here is they never break the trust that was given to them by their investors. However greyscale are a custodial service to most of them then they could take control over the trading market as a big whale if they intend to.

I can't imagine they hold 500,000 BTC Worth $8.5 Billion Currently Owned By Grayscale

coinbase's bitcoin holdings are roughly double the size of grayscale's. these stats from ~ a month ago shed some light on the current spot exchange situation: https://cointelegraph.com/news/five-mega-exchanges-hold-10-of-bitcoin-s-entire-supply

Technically they could, but since when did bitcoin provide dividends though? You're not investing in Grayscale, you're investing in bitcoin through Grayscale. There's a significant difference.

I feel like nobody has correctly or sufficiently explained what Grayscale is and what it does. Here is my explanation:

What is the Grayscale Bitcoin Trust?
The Grayscale Bitcoin Trust is basically an ETF. It's sole function is to own bitcoins. It does not have any income and it doesn't make a profit. It just owns bitcoins. It is not a custodian. It doesn't hold bitcoins for you in an account.

As an ETF, it has shareholders. Each shareholder owns a proportional share of the assets of the ETF (primarily bitcoins, of course). The shares of the trust can be bought and sold. There are currently 540,935,800 shares and the fund holds about 515,000 BTC, so each share is worth a little less than ¹/₁₀₀₀ BTC.

Where does the fund get its bitcoins?
The fund acquires bitcoins by giving accredited investors shares of the fund in exchange for bitcoins. So, for example, if you deposited 1 BTC into the fund today, you would receive about 1050 shares of GBTC. As a result, the total number of bitcoins held by the fund would go up by 1 and the total number of shares would go up by 1050.

Investors are willing to deposit their bitcoins into the fund because they can make an instant profit of about 15%. For example, 1 BTC is worth about $18k, but the 1050 shares of GBTC they would receive by depositing that 1 BTC are currently worth about $21k.

Restrictions
There are some restrictions.

• Anyone can buy and sell the shares on the open market, but you must be an accredited investor in order to receive shares by depositing bitcoins into the fund.
• An investor that deposits bitcoins and receives shares cannot sell those shares for 6 months.
• Shares currently cannot be redeemed for bitcoins.

Why would investors own GBTC when they could own BTC directly?

• GBTC can be held in a retirement account, which could mean that gains are not taxed. If you are expecting a 10x return on your bitcoins, you might consider holding GBTC in a Roth IRA instead.
• If you deposit bitcoins into the fund, the shares you receive are worth more than the bitcoins you deposited.
• You can make money by arbitrage from the difference between the value of the shares versus the value of the bitcoins they represent.
• Convenience.

They don't "own", but "partly own". They don't control those companies like how you're trying hard to misinform everyone that they're like the Bilderberg Group.

Grayscale also owns losers in that portfolio, like the shitcoins, Bcash, Zcash, Ethereum, and Ethereum Classic.

Is there a similarity between what greyscale is offering to their customers interms of btc services and that of PayPal! (Sorry I had to digress a little) because I see they are custodian of such huge amount of btc and yet people don't seem to criticise this action the way they lay it heavily on PayPal, or is it that some how the owners of this btc or investment have access to their private keys? Just wondering.
