I would change that the price would not be that stable anymore because with the price being stable bitcoin becomes really boring and there is not much to do at this point. I would not know how I would do it but I would make sure that the value of the bitcoin would change more often.
You then give people the chance to make some more money more often.
everybody wants a more exciting price which is also preferably only a rising price and never comes down.
but sadly this is not something we can change and it is more of a investors decisions to buy or sell and make it volatile or stable.
