If you don't get suitable bearish then you can start depositing bitcoins with DCA method and if you get low price of bitcoins during deposits regularly then lump sum buy may be more useful for you to get more holding in less time.
At least it seems that you understand the three methods, even though you seems to be conceptually mixing them up at the same time.
Your understanding is quite different from the point JayJuanGee highlighted on his post because if I can remember correctly he was clarifying you about the various accumulation strategies because you were mixing up the strategies and still after reading your post you are still mixing up things by getting yourself more confused the more, however I'm curious to no what you meant by having a separate portfolio, do you mean that your plans is having a seperate portfolio for each of the strategies?, don't messed up your investment do to lack of proper knowledge about how each of those strategies works.
I wonder why you would even talk about having diverse investment portfolio when you have not even been able to to arrive at your "Fuck you status", and even if you have arrived at that point there is no need getting a separate one since you already have an existing investment, so instead you can continue adding more.
Someone can argue that if you have enough money to convenitly buy a large amount at once then what is the essence of stressing yourself to do DCA every week or monthly.
For me I consider that argument to be an irrelevant one because everyone has there definition of a huge amount, so let's take for instance somebody who has $1k and claims to have a very large amount, do you advise such person to stop accumulating Bitcoin for years after investing the money?, is actually obvious that the argument will have a negative effect on people towards getting to there "Fuck you status".
