I don't see any problem in storing any amount between $50 to $1K, depending on your needs.
If you aren't going to store big amounts, it doesn't make sense to make a crypto enabled phone in the first place.
If you aren't going to store more than a thousand dollars, an Iphone or a random Android phone with "green address" app just do the same thing already.
Anyway, this is a good advertisement for both samsung and crypto and any attention we get is good. That's how I look at it.
