Hello,

if I am using several Monero receiving accounts (like “cash”, “work”, “trading”, “mining”, “donations”) and for each of the account i have secondary account into which i repeatedly sweep my receiving account's balance in order to churn/mix my XMR (e.g. cash -> cash2nd).

What if:

A) I "combine" the XMR again in the second "level" of my XMR accounts (account called common3rd):

cash     -> cash2nd    -> common3rd
work     -> work2nd    -> common3rd
trading  -> trading2nd -> common3rd -> 3rd party (big payment which would combine most/all outputs)

B) I split each churning/mixing transaction into several a small outputs:

cash -> output 1 - cash2nd
     -> output 2 - work2nd
     -> output 3 - trading2nd
and then spend from all these 2nd accounts in one big transaction

Is better (anonymity-wise) A or B and why or you suggest better direction?
