I proposed an investment strategy recently.

I underlined that coins with greater market cap have an high correlation and that the investment strategy during flat period should focus to the anti correlation pattern.

Once you identify coins that show an inverse correlation pattern you can speculate in the short period being able to gain during flat market.

Define your threshold like 3% or 5%  and start conversion cycles from a coin to the other when it decrease by a 5% factor and to convert back when the opposite occur. This way your money will likely not increase a lot but the number of coins will increase by a 5% market each cycle that will result in a big gain when market will increase again.

Based on the fact that your grow is based on the number of conversion cycles it would be suggested to not focus your pocket in a single couple of coins but at least on 3 different couples.

Now the main question is that each time you earn from a conversion the seller may have lost. 

Is this not ethical ? I would say no it is the market.

In two weeks for example the progression for Orchid moved from 1560 to 1680.....not bad right?

I have other examples I can report if you like.
