30,000 BTC sell wall gets bought up in hours, with constant buying throughout its existence.
3,000 BTC buy wall doesn't get sold into at all.
Bullish.
Yes and no.
The 30k wall was during a plunge. So, very low price and lots of sellers needing back in.
If the guy had bought up to $420 or so and placed a 3k wall? It would probably get eaten.
