Other reasons why increased adoption does not necessarily mean increased price:

• Fractional-reserve banking. If you believe that Bitcoin is immune to fractional-reserve banking, you are being naive.
• Bitcoins, and other crypto-currencies and crypto-assets are much more efficient to transfer. For the same amount of economic activity, many fewer bitcoins are needed. The demand as a result of increased adoption would not be as high as you think. Especially with the huge overhang of hoarding that we have now.
