This is big buy orders (support lines) arrangement on Binance before they disappear from order-book.
One thing I don't like about Binance is they don't show the whole order-book or market depth.
They hide the big part of it from public and this lets the whales do what they want.
This is at time of current drop , there was a big buy on 6500 but they picked it up and let the price go down.
And this is current big buy order at 6400:
This is the reason why most of the time I put stop-loss under support line or Fib's levels they get filled then price go up. They pickup their big buys to let price go down and buy our cheap tokens then sell them a little higher to ourselves. Yeah.
I must setup a trader BOT to save my money.
