Mass adoption of a singular cryptocurrency (Bitcoin?) will be achieved when all or most of the following happens:
1) A single, unified cryptocurrency is collectively recognized on a worldwide scale by the majority of merchants, vendors, and users as a form of payment for products, services, and local currency exchange (if needed)
2) Marketcap inflates and scales to some fairly stable level with much lower volatility.
3) Inflation rate falls below 1%
4) Highly-decentralized proliferation of mining and nodes worldwide achieved through breakthroughs in inexpensive, low-power mining equipment (e.g., I imagine a future world where a small mining chip is in every household router, business routers, etc.)
5) Onramps from local currency --> cryptocurrency EVERWHERE, INEXPENSIVE (< 1% conversion), and FAST
6) Faster to make a small payment with the cryptocurrency than with traditional fiat/card (like almost instantaneous with offchain transaction, using nothing but a cell phone or dedicated device, etc.)
Achievable? I think so, and many other people do as well. Many of these things are already in the works, others will just take time to breakthrough.
Yes, massive adoption is achievable and will overcome all the obstacles as time goes on.
1. A single won't ever possible as we have plenty of cryptocurrencies (if needed right)
2. Will be happen in the future if the price hit higher point such as $5000-10000, make market cap bigger which results stable price.
3. What kind of inflation?
4. Can be, but still need expensive cost, people to run it and maintenance.
5. Maybe about 60-70% already done.
6. Absolutely.
