I do like that sentence too but, storing it gives you the impression the value will be stable and not fluctuate. If I saw that slogan, I would think that my $100 I put into my DigiByte Account will always stay $100. This is not the case. Simply calling it a Digital Currency, in my opinion is enough. It tells you that it is a medium of which you use to pay for services or goods and that it is digital - meaning can be transferred electronically. The issue here, is over complication. But once again, this is just my opinion.
This is a very good point!
