You have to remember that even a guy who puts 10% of his salary into bitcoin, it will take him 10 years to reach 1 year of his salary invested into bitcoin. I consider 10% reasonable if your discretionary income can tolerate it.
There are folks who are investing into bitcoin at much more whimpily than 10% per year.. so it is going to take them a while to reach over-accumulation status, perhaps even more than 20 years.
With the right opportunity, a person can position himself/herself into a large Bitcoin investment that will neither affect him/her psychologically too much in case the position goes against him/her, because he/she knows the probability of going lower is very low. But that comes merely with luck, and timing.
Those opportunities come during bear markets, and if they do come during your lifetime, be absolutely sure to use a LARGE of your savings, then purchase as much as you can afford during the succeeding months.
But during the current phase of the cycle, just DCA with a small amount. The size of the investment won't bother you completely and make you emotional/panic sell.
