The key event of 2013 was the Cyprus crisis where they did bail-ins without warning people. Lots of people lost their savings and some businesses even lost their payroll money and couldn't pay their staff.
That led to people saying, "be your own bank, and use bitcoin, at least the govt won't be able to seize it". And worldwide, this created interest in bitcoin.
I think that's bilge myself. Same goes for Greece. It might have been used as an excuse to initiate a pump by the same old suspects but that's about it. Both events are hardly ever mentioned any more. I'll bet no more than a few hundred Cypriots or Greeks actually used it for what Bitcoin fans believe they did.
As for the original question I'll sit and do nothing. We come and go in waves. At some point another wave will arrive. It may have nothing to do with the halving at all.
