The symbol is a representation of a digital coin - in the middle, the K (from Kriptomat) intertwines with the Bitcoin symbol. Both of them make a unit representing the central element of an Ethereum coin.
Outwards, the 4 little corners outside the Ethereum suggest the idea of a box, implicitly of "store" from the motto. The two circle arcs on the left and right and their top&bottom smaller circles convey the idea of movement, of a transaction (the buy-sell polarity from the motto).
The outermost circle is a representation of the outer boundaries of a coin.

The text matches the weight and style of the symbol.

The colors are chosen to convey the idea of trust (blue) and maturity (both blue and grey).
