And by adopt I mean adopt for payments, not hodl it as an investment.
That's not really the paradox behind Bitcoin and doesn't get to the root cause of the problem. The real paradox is - as Bitcoin is adopted by more people, the transaction fees goes up and the network takes longer to process the increased levels of transactions while also burning a lot more electricity than comparative payment networks. If Bitcoin was much cheaper and as instantaneous as existing card networks, this wouldn't even be a discussion - people would have naturally moved over and Merchant adoption would be much more widespread, however the claimed benefits are simply not there. I find that Bitcoin is very good for one thing - moving reasonably large amounts across borders, it simply is not fit in the current form to handle the degree of small scale transactions that take place each day.
