I agree that positive thinking can help result into positive things or outcome too as how they also say that, your state of mind should effect what is outside rather than outside forces effect your thinking which may result to you acting harshly over things which you do not have control of.  Same with bitcoins and cryptos in general, we can't really do anything about its value decreasing when we wanted it otherwise or vice versa and so the most that we could do is to remain hopeful and positive by celebrating small victories of this market like its increase in value since it's lowest deip this first few weeks of 2018.  We should also remain hopeful that despite banning or pulling out of certain countries from this kind of trade, there will still be others who may realize that cryptos are truly a good thing and helpful to one's economy. They just have to be open and see how it is affecting positively the lives of those who are very active with trading and investing crypto.
