Big Buy/Sell Order shifts ?
Whoever watches this has to be aware that Orderbooks are no more then mists or fog.
Developer updates? Scams make more update noise, so that's a weak sign at least.
Big Volume Traffic ... when it crashes, the volume is higher. Sure sign to get the fuck out. This is usually way past the first significant price move.
... overall in summary, don't trust those signs or learn to read them better.
If anything, our beliefs about crypto need to die.
Some, not all.
