For the time being,I would suggest that it is preferable to be cautious rather than unhappy. Despite the fact that there are many coins that looks promising and, more importantly, appear to go with a large profit in a short period of time, I dont opt or rarely acquire them. Moreso, one can choose the assets that have been in the market for a longer period; while they may take much more time and yield a lower return, I believe it is easier to purchase them.
