shinedust situation

the only way now to stably get shinedust is by sharing a 4 diamond card and get 720 everyday. or else you have to hope to get lucky on high rarity duplicates or hope there are some random event that gives you shinedust(like the one starts today) which you cannot stably gets the dust everyday. Is there any way to manually get shinedust everyday? Cuz I have to share for almost 3-4 weeks to complete one singular 2 star trade
