I can't predict their very beginning but by being lucky enough to pop in the right day and the right time of day I can spot them on the way up by the sudden surge of sustained then 1 or two green surges(blips of green higher) of buy volume uncharacteristic with a normal trading day. I'm a drive by trader meaning never sitting for more than 10-15mins to process some trades and sometimes missing complete days all together since it really is just a hobby for me. As a result, I miss many plays I could have spotted, oh well. This time I was only trade 200 at a time just to test the waters in Potcoin as I'm a long term investor already and just started round tripping it for the past couple of months since it's previous pump.
Thank you for posting and your question.

Thanks for your answer, I can see the small spikes in volume, makes sense.

I'm going to add a picture from the October chart at the bottom of this post to better illustrate my answer.
