Knowing the nature of what the market is, we must be able to related all the necessary assessments expected of us before making an investment, after doing all these, there must be a cogent reason to why we must invest at a particular time and hold, buying and selling as we already know is a continues process, the more we go in doing it the higher the bitcoin value turns to be because of its increasing demand, so setting a particular time frame to buy or invest and then taking the right position upon our investment asset will all make it more profitable for us, now on trading, we may have to trade base on the personal convictions we have towards it, if we truly understand why and how to trade, manage the risk in trading and lots more, we are also going to make some catch at the cause of doing so over time.
When you said we must have a cogent reason why we must invest at a particular time makes you sound like a trader and of course you are talking about trading and that is not why we are here, trading is not the reason why this thread was created and so we should avoid anything that will try to confuse or mislead newbie. However, anyone who calls himself or herself an investor should not have another motive or reason other than accumulating and holding for long term so as to make profit because when you said a particular time it can be timing the market to dip so that once they buy and the market appreciate they will sell off which is trading entirely and that is unlike an investors because investors buy at any given instance of the market using the DCA method. Moreover, how do you have a conviction for something that you are not sure of and even the trader itself is not even sure of the conviction he or she has I mean trading it is really crazy and it should be avoided with all cost.
