I dont know why many people scared to the decreasing of bitcoin. Your question is when do we sell our coins? The answer its up to you. We do not know the flow of bitcoin, if it is increasing or decreasing. If i will ask i will sell my bitcoin when it reaches very high. I can wait and you do not need to panic and sell immediately your bitcoin because it decreasing. It is just a matter of time and being panic is nothing. Bitcoin at it lowest rate is okay because its normal. It is like this season is the buying season and when the bitcoin rises, it is the selling season. Selling bitcoin because its getting low, that is not a good strategy. Im just saying my opinion.
