What will the future look like with Bitcoin in 10 years?

Once bitcoin is hopefully widely adopted everywhere and is a lot higher in price, do you think its value will stay relatively constant besides going up when there’s inflation with fiat? Would that make investing in other assets like certain growth stocks a better place for investing money at that point if I want to make a higher ROI? Also how will the average person that’s not tech savvy hold their Bitcoin? Do you think they will use an app like cash app or a traditional bank to hold their Bitcoin instead of cold storage? I know nobody can predict the future, but what’s your best guess?
