So they keep the stable coins waiting and instead of buying now while the price is low, they are waiting for .. a certain block to pass in order to buy?
No. If they do that it'll be just a psychological tactic that'll actually do a big scale pump and dump. Which is not unusual at halving events.
Imho the real price growth may happen only when miners will not be willing anymore to sell cheap the much more hardly earned coins.
The exact same thing which is happening to the oil market.
People were waiting for it to reach negative territory looking to reap on an opportunity to get massive gains once it recovers. And it will recover because the world runs its global businesses on it.
I often wonder if small companies sometimes make deliberately outlandish statements just to garner media attention. It now doesn't matter whether their analysis is right or wrong, they've got their free publicity now.
My personal opinion is that the dollar figure you place on so-called "stablecoins" is utterly meaningless because many of them likely aren't fully backed (as the centralised companies that control them would have you believe). And even if they were fully backed by real-world assets, it's still just a cheap duplication of the value of the underlying assets. You're literally trading IOUs for something that may not even exist and have to place full trust in a company that, not only does it really exist, but also that you have a genuine and tangible claim to the funds the stablecoin supposedly represents. Why would you even get involved with something that shady?
Stablecoins are a scam. One of the most ridiculous things in all of crypto.
Stablecoins are a scam, as we have all witnessed what tether has done and is continuing to do to bitcoin and cryptocurrencies as a whole.
They do cause massive disruptions in the price when there are a sell off and a buy back on a whim. Thus the sharp volatility swings in the crypto market ever since the concept of stablecoins came into existence.
