As you say bitcoin has touched "the bottom" $ 5800 this is the time you should buy rather than sell. Please buy bitcoin or altcoin. By the end of the year you will definitely be profitable
If I were in your place, I would say so. In my opinion now it is not clear what will be the cost of bitcoin in 2018. If you believe the forecasts, then the value should increase and reach the level of 20000, but for some reason I do not believe it. This year the predictions come true only for the worse.
