It is not necessarily a good practice to hold a lot of value back for dips that might not happen.. even if some guys have done it and have had some success with those buying on dip funds.  There are trade offs, and if the guy is new to bitcoin or he does not have a lot of discretionary income, then it may well not be a good idea for him to be holding back very much for buying dips that might not happen, instead of staying focused on ongoing, persistent, consistent, regular and even potentially aggressive buying of bitcoin and the building up of his emergency funds and other aspects of his cashflow management system/practices so that he can figure out an appropriate level of aggressiveness balance in regards to his regular buys, especially when guys have so little discretionary income that they might not even be able to afford the buying of $100 in bitcoin per week, and then they are going to want to divide that in to funds that they set aside for buying on dips that might not happen,... makes little sense for the low discretionary income folks and the guys who are in their first year or two of accumulating bitcoin to be engaging in such practices of holding money back to buy on dips that might not happen.
