If you are looking for all the above step then you can definitely follow the rule for DIP and HODL
There seems to be a bit of gobble-dee-gook in your description regarding how to assess the value of an asset and if it may well have long term prospects. Let's stick with bitcoin rather than talking about any other asset or token or whatever because this thread is not regarding talking about various shit projects, and likely there is a bit of an assumption here that bitcoin's fundamentals are actually good. We need not go through that assessment either, but we still might try to consider whether we are in a dip or not or if the price is going to dip more. Of course, there is a feeling of getting more value if buying on dips, but also if your investment time horizon is long enough, whether you bought on dips or not might not have made as much of a difference as the mere fact of buying and NOT really hesitating to buy on a regular basis until you meet your investment goals - and even your investment goals might be changing if you happen to be a young person and you have a long time horizon to invest before you start to draw upon the investment.
So for example, if you investment timeline is anywhere between 20 and 30 years, you might do some lump sum investments into BTC, just to get started, then you might set up some regular small amount of regular DCA and you might set aside some value as well to prepare to buy on dips. If the BTC price goes from $38k to $380k in your investment timeline, it might not have mattered very much if you bought some of your early BTC at $38k or $45k.. and furthermore, if you feel like you do not have enough invested, you may well have been buying small amounts of BTC for that whole time and some of your BTC buys might have been as high as $380k...
So in the end, if you end up going from 0 BTC to perhaps having 4 or 5 BTC, you might still feel good about the ongoing persistence that you had over time to just continue to accumulate... or maybe at some point, you reach 10 BTC, and you feel that you really ONLY need to accumulate 4-5BTC to feel comfortable, so you feel like you have twice as many BTC as you need, so at some point you might either stop accumulating or start to sell some of the excessively accumulated BTC.
I doubt that we are in a 2018-like situation right now (remember that 2018 was a down year.. the whole year)..
Seems to me that it is more likely that we are still in the middle of a 2017-like situation.. (perhaps a 2013-like situation) which signifies that the top (so far $64,895) has not yet been reached for this particular cycle.. but where the top would be might be another question.
Will the top be just a small portion higher, and unable to get above $100k or might we have a top that goes above $100k and so high as $200k to $300k, and sure there are possibilities of going higher too in this particular cycle.
Of course, there are no guarantees regarding where we are at exactly, which implies that we cannot be sure either regarding the direction that we might be going from here, and so people are going to come to varying conclusions regarding what they should do regarding their own strategies based on their assessment of where they believe we might be at.
