Why 'Earning' rows don't increase my spendable balance (and why balance-after shows a dash)

This is expected. Daily ROI is recorded as Earning rows, but that profit accrues into the investment's current value — it grows the position rather than immediately hitting your spendable Balance. That's why an Earning row leaves your Balance unchanged, and in the ledger its "balance after" column shows a dash (—) instead of a running balance, because no spendable-money movement happened. You actually receive the money as a single Cashout transaction: when an investment matures (or after you request an early cash-out), the platform pays the full current value — your original principal plus all accrued profit — into your Balance exactly once, and that is when your spendable Balance goes up. So Earning = your position growing on paper; Cashout = the profit landing as real, withdrawable cash.
