Here is a quick tip...
aug 1 2017 bch is launched...lets say around $200
it goes to $900 within a few weeks, people buy high and are dumped on...
now from the $900 buyers there is 2 types of people, panic sellers on loss as it dropped back to $200 and the average down smart investors
the smart investors kept buying on every dip , accumulating more and gaining cheaper entry point than the original $900 they paid.

The same is happening again but on a higher price point, reason being....
demand has increased as more epople are becoming aware that btc is now segwitcoin and bch performs much better overall.
So the smart buyers from $2800 are buying now and lowering their entry point, while noobs that bought high are selling low and calling bch a P&D lols.
