We all know what did happen in Sept 16,a big fall of BTC and nearly spike down to 2.800.And today BTC have made it passing recovery checkpoint 2 days before Big down Happen (Sept 14).but the price wont go smoothly to the top without any waves and corection,there is a lot of waves and you know that is ussual behavior of the chart.
2 Waves have nearly done after reaching back to $4000 level.and i think there is will be the 3rd waves coming.and even in 2 down direction waves,we all can still make profit by playing ping-pong.just like me making 6 trade in 2 days and making 12% profit while the chart go down.Waves is essential in chart and you must be friend with it
