2. Liquidity Needs: you need to know you liquidity need before you start investment like what your daily expenses be and the amount of emergencies fund wey you suppose keep to avoid investing in bitcoin and end up selling when it is low and at loss because of emergencies.
This seems confusing to me. You don't need to have a lot of knowledge before you start investing. Just know what Bitcoin is and how it works? Or at least enough knowledge to trust Bitcoin. If you spend too much time learning, you're delaying your investment and missing out on buying opportunities.

Liquidity is a necessary one that helps every investor balance up his investment plan. even though the OP did not do justice to explaining it well enough, ensuring liquidity is necessary both in business and investment.. by liquidity i presume that the OP is referring to keeping money in circulation such that there is always availability of funds at whatever moment you are in need of it to either buy your bitcoin or to use for your expenses so you are not tempted to sell your coin too soon.
For fixed income earners, doing automated deposit into your investment account will help the investor stay disciplined such that it becomes easy and possible to do effective accumulation in the form of the DCA strategy once you receive your pay.
