The most important thing is to start consistently, not the amount of Bitcoin. To start any investment, you should first have money, sufficient knowledge, or absolutely perfect market conditions.
You don't need to understand everything about Bitcoin before you invest in Bitcoin, and you don't need to start your investment in absolutely perfect market conditions because Bitcoin is highly volatile, and you don't know when the market will be favourable for you to start your Bitcoin investment. If you have a source of income that guarantees you discretionary income, you can adopt the DCA strategy and start your bitcoin investment weekly or monthly based on the one that is convenient for you, and you need to set aside your backup funds or emergency funds. In case you have any emergency you didn't plan for, you can depend on your backup funds or emergency funds to solve your emergency, and it will not influence you to sell your bitcoin.
The only time we can say there is an absolutely perfect market condition is when there is Dip else there is nothing of such especially for an Investor because their target is always long term investment and so using the word absolutely perfect market condition seems like a trading term because as an investor you don't really need this because the dollar cost averaging is always there to buy at any time regardless of the market condition. And don't complicate or mistake back up funds to emergency funds because they both have different task even though they are both used to solve problems but the problems they solve differs.
The most important thing in investing is to start investing consistently, regularly and in a planned manner. You should not start Bitcoin until you know everything, it can be an unnecessary obstacle. It is better to start investing with some basic knowledge. Perfect market conditions are applicable for trading, it is not reasonable or necessary to wait until perfect market conditions for investing. Investing requires not only money or strategy, but also mental preparation. Because investing requires mental capacity to withstand market fluctuations. It is necessary to maintain consistency in investing, but you should also pay attention to the amount of investment and its consistency. It is not right to put yourself at financial risk. Investing in the DCA method helps you reduce average costs and reduces the impact of market fluctuations.
