Merchants don't adopt Bitcoin because their clients don't use it. Clients don't adopt it because merchants don't support it, and people want to have a payment method that can be used anywhere they go. How can this vicious circle be broken? Who will make the first move?
And by adopt I mean adopt for payments, not hodl it as an investment.
Customers have to make the first move Obviously, when the customers or clients would feel the need of crypto payments no matter how small proportion of customers, it will always drive the merchants to add this as a payment method. It's because merchants see everything based on their profitability and cost, therefore, customers have to drive this change always. I think paradox is when you have customers who want to pay in bitcoin but you have a supplier who doesn't wants to receive in bitcoin, this leaves you open to a great extent of risk.
