Why not more tiers with less difference between them? e.g. 250 1000 2500 10000 25000

Why not a compromise between yes and no: kinda phase out moving minimum up to 250 and maybe later to 500?

Please please please keep them, the other tiers are so expensive I wouldn't be able to afford to make regular questions

I think they serve a role for now. Wouldn't be terrible to remove them once Ṁ1,000 feels more like what Ṁ100 used to, but psychologically (and balance-wise) it hasn't caught up.
