I like this your idea, but i don’t think hiding the price really solves the real problem here because some investors haven’t really learned how to handle bitcoin’s volatility without letting it influence their decisions emotionally so if the person’s conviction solely depends on not seeing bitcoin drop, then how strong was that conviction in the first place?
The people who have been able to survive multiple cycles in the past usually aren’t the ones who found the perfect app to help them hide the price of bitcoin, but the ones who decided on a deep level that the volatility of bitcoin is the price of admission for the asymmetric upside that they have chosen to believe in.
you got the points, there is a lot of people trying to use several tools just for tracking his assets. in case they are hiding the price, when opening another apps, they will see the price of coins they hold. So, one tools will not help anything if there another tools that works in other sides than this tools. It's mean they can track total assets, current price, current dollar value of their assets.
If someone wants to be an investors, they just need to forget anything after buying, no any noise on their device, such as notifications or easy to open apps just like mobile wallet, exchange or others. saving to wallet and never tracked that, until you feel you got much money than others holders already.
