I wanted to go $480 but had to switch back to $500.
Seems like my spidey senses woke me from my sleep right almost the optimum short term long opportunity. But looking at these single 1700 BTC sell orders coming out of the blue and slamming into Bid wall on Stamp, I didn't fancy taking the bite at anything other than the most extreme sell-off down spikes.
After every previous Bitcoin crash, the spot price has found its way back down below the 200 day Moving Average. If that were to happen tomorrow, Bitcoin would have to go to around $450-$480.
