That's RETF, which is a "marketmaker fund" that rarely flips a profit.

The one i mentioned is BFRF, not RETF. Has paid one each month since its IPO started (the total amounts are smaller in the beginning because less bonds were outstanding, but per bond amounts are always 0.01): https://www.therocktrading.com/en/funds/listdividends?id=BFRF
