Don’t buy into the wall.
Wall is put there by the whale to force people to sell lower than that wall price.
Why? So the whale can buy more safex
Effect of buying into wall, the whale makes BTC and is able to buy more off sellers who are selling below the wall price. In other words the whale profits off you buying their wall
What to do. DON’T buy into the wall. Starve the whale.
What then? The whale will remove the wall.
What do we do? Buy at a price below the wall if we want more safex. Thus starving the whale.
In the long term buying the wall would have no effect anyhow, and you bought safex at a higher price than you needed to and the whale has more safex to do the wall trick later on.
