That coinbase has some nice buy support. Not sure I've ever seen that much depth in coinbase's orderbook before.

Thanks for the chart. As they say "liquidity begets liquidity".
If I were the skeptical type, I would speculate that this is coinbase using some of their recent funding in an attempt to lure more volume trading on their platform.
If I were the more conspiratorial type, I might suggest this is just fake walls...
That's quite a large rise in volume out of nowhere... Why?? I like your "skeptical type" answer above, coinbase fluffing their own orderbook?
