Oh yeah, I understand :) As of now one account feels already a bit grindy for me, so maybe later I'll have some others too. Also often the drugwars fight reports, "see what I opened today on Steemmonsters", etc. posts are not seen as high-quality posts, so it is indeed a good idea not to have them on your main account.
I just realized that on multiple accs you could farm the steemmonsters dailies multiple times. If you gather the cards to one of your profiles you can have so powerful decks...
