Human Factors
Departed ZZZ direct to ZZZ1 via local Special Flight Rules area. Had flight following from ZZZ to ZZZ1 at 3;500 ft. Prior to the ZZZ VOR I visually saw traffic at my 8 o'clock converging. I then got a call from ATC to watch for traffic who they where not talking to. The traffic continued towards me with out diverting. ATC gave me a Bravo clearance and I had to do a right 360 to avoid traffic. He then proceeded in front of me for local Speical Flight Rules area. When entering local Special Flight Rules area we got a frequency change. When making my first call I asked if the other aircraft was on frequency. He was and stated he saw us but that I was at the wrong altitude and I should have been at a different altitude.
Bonanza 36 Single pilot reported an NMAC event due to wrong altitude.
