I sold everything. Hope to buy back cheaper, when this whole core / xt-thing blows over.
That's good news for all the hodlers. I've been dead wrong on almost all of my trades. Probably Greece will default on the 5th of june and a lot of Europeans will get out of and into BTC skyrocketing BTC-euro value.
You are brave. I don't know when or if the price will start upward again, but from my experience in the past, it can happen very quickly. In my case it can take me several weeks to transfer any significant amount of fiat to the exchange to transfer back into bitcoin. I hope that either you have much faster method of transfer, or if you're just leaving your money on account at the exchange, that your exchange of choice is more trustworthy than most.
Best of luck.
