Making a new coin as a savingsaccount, possible?

[TriggerHappyCoin]

Hi,

I was thinking, is it possible to create your own cryptocoin (via waves for example), and store all your money into it. This way you wont have the regular interest (in europe a stunning 0,01%!!). It will not be effected by dips and/or highs on the cryptomarket, it will just be sitting there for your own pleasure. It will be your own savingsaccount on the blockchain.

Are there risks involved in this idea?
