If you don't have enough and you start to withdraw from it, at some point down the road, you are going to realize that you are fucked because your bitcoin holdings is not holding value well enough to sustain your withdrawals (or alternatively, you have to lessen your withdrawal rate until your holdings are going to grow), and so in either case, you might well conclude that you made a mistake when you star your withdrawal based on an erroneous assessment of having enough when you don't.
You're absolutely right here! There are two things that i have kept as a priority from what you have said here.
1. If my investment is not strong enough ill not withdraw because it is needed to be treated like an investment and not an ATM.
2. Never rely on one source of income if I want to tap into my investment because multiple sources of income will quickly assist in replenishing the investment once we eventually tap from it.
3. If am to withdraw my investment I should have a realistic withdrawal strategy before thinking of doing that.
This is also applicable to all investors because it won't be fair if we tamper with our investment without a proper way and unfortunately tap into it during a downturn which will make us lose potential profits in the future.
