Not buying a single bitcoin until price hits $20-30 dollar. For the current transactions, a 300M market cap should be sufficient, so the price needs to fall by another 10x ...
I don't think it will go that low this current ongoing crash, we'll probably bounce around 120-130, back to around 180-200, then decline again to 60-80 before returning upwards a little again...
You could wait for a 3rd crash that goes lower but that could take a while. These are the indicators for the upcoming period, they were there before the coinbase trickery, and they are still valid now.
There's still a risk of complete collapse of course, so the safe bet would be to invest in proper smart and fair digital currency like ripple or things like that.
