Dust and super small transactions should be pushed to an altcoin, there is no reason to keep them on Bitcoin and pay fees higher than what you are sending to get it through in a decent amount of time.
actually what for sending a little amount?
i will stick to keep using bitcoin no matter how small the transaction it is (a reasonable transaction of course)
altcoin are not as popular as bitcoin , that is the problem ,
0.001 the lowest transaction i usually do and i think it is a reasonable amount instead 0.0001 or so.
