(15)To prevent market abuse to the maximum extent possible, persons professionally arranging or executing transactions in crypto-assets should be able to refine their surveillance systems and to detect patterns of repeated behaviour, the aggregate of which could, considered as a whole, result in a reasonable suspicion of market abuse. Those persons should therefore be required to analyse suspicious orders, transactions, behaviours and other aspects connected to the functioning of the distributed ledger technology which did not lead to a STOR and record such analyses. Such records should also assist such persons in evidencing compliance with Article 92 of Regulation (EU) 2023/1114 and should facilitate the performance by competent authorities of their supervisory, investigatory and enforcement functions under Article 92 of Regulation (EU) 2023/1114.
