Consolidating: pay once now, or per coin later
Consolidating sends every coin to one new address of your own in a single transaction, so later you spend one input instead of many. It also links those coins together on the public ledger, so only combine coins from the same source.
Every withdrawal to your own wallet becomes a separate coin (a UTXO). Spending a coin later adds the same number of bytes to a transaction whether it holds 5,000 sats or 5 bitcoin, so the fee falls hardest on small coins. Stack $10 a week into cold storage for a year and you may hold 52 coins that each cost something to move.
This planner shows that cost at a range of fee rates, the smallest withdrawal that keeps it under the share you choose, and what consolidating in a quiet period could save. Fee rates in the future are unknown; the table shows a range rather than a forecast.
