You don't have to have it all before you start your Bitcoin accumulation journey, all you just need is a source of income where you can be getting your discretionary income from, and it's through there you invest from, so you don't necessarily need to have it all before you start, along the line you can work on a way to improve your finances so that you can be more comfortable while investing.
The fact is that we can't have it all. I am not expecting anyone to use that as an excuse for not starting to invest in Bitcoin. As long as someone has a source of income, they can immediately begin their Bitcoin accumulation journey from their discretionary funds. Waiting to get a certain amount of money before starting to invest should not be the reason someone misses opportunities. In fact, no amount of money is too small to start Bitcoin investment. It is easy to accumulate Bitcoin gradually, even by using the DCA method.
What’s also important is that nobody can predict Bitcoin’s price. Let’s just imagine, recently, a set of people predicted that Bitcoin would drop to $85K in the first week of the month when its price was around $108K. But look at where the price of Bitcoin has increased to today. Nobody should wait for the "perfect" time to start Bitcoin investment because, as it seems, by waiting, you are missing out on some great opportunities.
