yes they did so but....... yestedary.....today.....btc not moving much ,volume kinda low still

Nope, they can't fake that, it is as true as it can get. Their addresses are well-known and these institutions know better than to fool everyone.

Why you not try it yourself before speculating? I believe you will got contacted tons mail ask about proof and got blackmailed too.

Both of them, you can't know it's real if they didn't showing the proof. If it's from big company, pretty sure it's real since the address are known used by them and anyone would ask to verify the owner of that address.

These companies have investors behind, and are subject to recurrent audits, where the purchases are going to be verified. It’s not very likely that they’ll make a public announcement in a terrain that is not tied to their core business, for a few minor headlines here and there, only to come out looking bad against their stakeholders for not being honest about it.

These are usually considered bullish news, so if there's anyone to profit off them, it's the institutions themselves from the future pump caused by their hype.

Announcing you've invested $50k of your funds in BTC as a company is one thing; announcing that you're investing a significant amount worth millions of dollars in BTC is a big risk no big name is willing to take. Imagine publicly announcing a fictive purchase of $100M worth of BTC and then IRS asking you where that money is being held. Nobody would be stupid enough to do that.

You don't need to purchase all those coins in an incrementally higher-priced bulk order. It could be a DCA that's been done over the past few months/years, an auction or a direct purchase that doesn't require a direct, visible influence over the prices. Purchasing $10M worth of BTC in a bulk order is a stupid idea, because all you'd really do is buying Bitcoin at an expensive price. The other option is to simply become a wall, but that could backfire on you. DCA or private purchase is the way to go for very large orders I guess.

Back when I used exchanges, I used to exchange alts to BTC in repetitive orders (say 0.01BTC/order). That way, I wouldn't become a wall nor did I have to purchase at incrementally higher prices.

It's either we believed these kind of statement from company or not. We can't really proved or disapproved. But it's not that important I guess, still a win-win for bitcoin whichever way we look at it.

And the only one that they are going to fool here is not the crypto market, but the company themselves if they chooses to release such fake news in order to make the public believed that they have throw this x amount of millions to bitcoin market.

Of course, the investments are audited. It is out of the question to be wrong. Otherwise, they will be manipulating the whole ecosystem, and that is certainly a big crime. Also, even if it is not about Bitcoin, we cannot under any circumstances be able to prove with certainty which company invested in what and how.

They bought by OTC not with Usdt or USDC. 
I think so, so If they bought trhough OTC Why the price went up?
