I haven't heard of any validators either. Maybe it refers to some centralized organizations that use bitcoin? Then it also has nothing to do with bitcoin.
I am talking about making a collude or some group in which they come to gather to manipulate the market. But, in my opinion that's not possible because BTC is decentralized so i think i should agree with you and my doubts as well.
Accordingly, it is important to remember that true bitcoins are only on the bitcoin blockchain, any ersatz bitcoins from funds are not true bitcoins, and may behave quite differently from true bitcoins, and have a completely different value. Therefore, it makes sense for yourself to choose only true bitcoins. No matter how big funds try to manipulate our opinion.
Yes, we should prefer to buy BTC and be boss of our own funds no just hand our money into the hands of BlackRock or any other company applying for ETFs. But at the other end a lot of people saying including me thinks that when these ETFs will get approved BTC will get hype.
