Actually there is no specific time to start, but as investors, of course we have special considerations when the best time to buy, and in my opinion the faster is better, this is because the opportunity for rising can occur at any time, the usual mistake is too often doing analysis and delay to buy.
well to be fair here sometime analysis does require time and buying when we're not done with the analysis could often be disastrous.
thats the thing with analysis, i think rather than letting the investment or trades become disastrous by buying the wrong coin or token its better to keep analysing.
after all we can be missing an opportunity and find new opportunity later on, the opportunity doesn't come only once.
if we always sought after opportunitites im sure that we will eventually find one.
however, sometime there's case where we need to make investment fast before getting overtaken by other because some investment might be limited like basically those presale or launchpad from the reputable exchange, if the risk is low, maybe it will do to not have analysis at all.
