Given that the Bitcoin price has historically been determined by market manipulation (wash trading at Mt Gox, issuance of unbacked Tethers by BitFinex, the current implosion of Celsius for issuance of unbacked tokens and wash trading), the modeling and analysis here seems spurious.
I particularly take issue with the assumption that the bitcoin price is for some reason going to asymptotically approach that of gold in any meaningful sense. Gold is an excellent conductor, and has uses in industrial and chemical fields in addition to its ornamental value. I certainly don't think my git commits have an intrinsic value on par with that of gold.
Additionally, the last reference you list:
Yorke, E. D., Fuks, Z., Norton, L., Whitmore,W., & Ling, C. C. (1993). Modeling the Development of Metastases from Primary and Locally Recurrent Tumors: Comparison with a Clinical Data Base for Prostatic Cancer. Cancer Research, 53(13), 2987-2993.
I see nothing referencing this source in the work, and find no references to cancer or tumors in either this post or the paper.
