 ## Useful
 
 How we do transaction inside pool of A amount.
+
 1. sort inputs by amount
 2. try to take 1 or 2 smallest inputs to satisfy A amount. Get 16 inputs if it's not possible using the same way
 3. Also you can always use transaction to merge your inputs with change (especially in 16 inputs case)
