please feel free to correct me if I am wrong (most likely am):

I'm interested in knowing how many SMSFs as clients because ultimately, the ETF will copy the most successful SMSF's portfolios in SeflWealth's universe right?

If we don't have that many SMSF (hence the reduced probability of even having successful SMSF portfolios in the first place), how do we know if the buyer of the ETF would actually get a winning portfolio? As we know in the funds management space, people do leave in droves when an investment start to underperform even by a tiny bit (just irrational most of the time, but sometimes for very good reasons too!).

Just not comfortable knowing that the SMSF ETF portfolio could be relying on only a handful few.
