Wide and modest, or narrow and richBitcoin / TetherUSBINANCE:BTCUSDTMarketFlowResearchBuy bce: epoch 3 earns $30 almost anywhere on the grid (72 cells); epoch 17 earns $151, but only in 4 cells. Both are kept. Within each loss family the network with the largest 90% zone is the first pick; ties go to more money. Then the richest network of the same family is checked: if it earns more than twice the first pick, it is kept as well and marked as added for money. For buy networks this rule mattered in four families. In bce, pos and focal, epoch 3 earned the same $30.27 across most or all of the grid — 72, 1,944 and 504 cells — because at that epoch money barely depends on W or θ. The richest epochs of the same families earned five to seven times more ($151.32, $211.01, $164.91) but in zones of 1 to 4 cells. In ladder, epoch 0 ($119.61) was added over epoch 6 ($27.84). Altogether 450 buy candidates → 22 networks, 75 sell candidates → 20 networks (three added for money). dice (buy) and focal (sell) earn nothing in any cell.
