I belive it was one of the triggers that caused this dump.
Might be the cause or not but this is just a delay just take a look on what happened on ETF decisions too where it do have those delays.We cant really avoid on having those
thoughts that this might be the reason or not but behind that no one knows if it did actually trigger something into the market.
A delay for what? But i think OP was right it might be the cause that triggers to caused the massive dump. Look what they did to ETF when they deny the approval of ETF the market starts to decline most coins. Though you might be right, we couldn't avoid such things to happen.
