Play it like the Martingale Master does. i will be starting to put buys in from the 700 area in all the way down to 400. If BTC has a strong push down, we are heading to complete the I posted earlier, along with my top call -https://www. Also check out my more lengthy post on Ether with the buy zone, it goes a little more in depth
How to utilize the Martingale strategy - When you buy in at the 700 range with the first % of your portfolio, with lets say 10%, the goal is to sell on any bounce up. Most probable would be a bounce from the 700-720 range up to 775-795. At which point you sell that portion. I then will put my buy in place again. If it keeps going down, my average buy in price will be lower as my additional buys hit lower. I can still play the bounces if it goes up and as it goes down, I get brought in at those lower prices. It works great.
