Good question. Last year was probably the turning point, when banks started imposing limits on cash withdrawals and restrictions on transfers (which I talked about in one of my previous posts). That's when I realized that I was safe anyway, as I could always rely on bitcoin.
All the changes described in this post happened before the events of last year, but it was last year that finally convinced me to keep moving in this direction and that I no longer have such a rigid dependence and attachment to the system.
