Is it true you get rainbow medals for selling 6* characters?

How many?

Have someone tried to not to be on during three days? Will it work if you are not in the game and you have already purchased something? I wonder. Will they give you a reward?

It does not seem to have anything to do with not being in the game, I have been in each day for months and I got the 500 as well.
