If you have set up a recurring purchase plan and wire funds into your Swan account, it is possible for your wire to trigger your recurring purchase plan automatically and purchase Bitcoin before you are able to manually convert it.
This only happens when either:
1.) You have a recurring purchase plan set up from cleared balance.
2.) Your recurring deposit plan is offset in time from your purchase plan (this situation can arise if you edit your plan previously).
If these situations, the proper amount of wired USD is deposited and settled into your Prime Trust account, but part or all of your wired funds are converted to Bitcoin automatically. Please check your purchases and deposit history for evidence of this.
