I have a tendency investment system. In the past 15 months, it has worked very well in the BTC/Ethereum market on Poloniex !

BUY and SELL
Let's see how it works for buy and sell. The following chart is for the buy and sell points.
If you invest 1 bitcoin, the balance will be the following. You will get about 9.8 bitcoins !
SHORT SELL
I do not use leverage here. For example, if I have 1 bitcoin, the eth price is 0.2 bitcoin, I only short sell 5 eths. So there is almost no risk.
The result is also very good. If you invest 1 Bitcoin, you will get nearly 12 Bitcoins !
If you both buy and short sell, you will get more than 27 times of your Bitcoins ! Your balance changes like
