Everyone has their own preferences when it comes to investing. So, it does not mean that you are investing because you have good cash flow, but you are not buying regularly or continuously to increase your portfolio. This statement may be a misconception for you in terms of investment. You do not have complete faith in Bitcoin. If you had faith in Bitcoin, then you would have continued buying continuously. In this way, you are only moving away from your target level. In terms of investment, everyone has the right to make their own decisions, but decisions should be taken after analyzing what is right and what is wrong.
People are different and they can have difrerent mindset and investment approaches but in my opinion, if your finance is good enough, and you feel like you already invested enough in Bitcoin, you can stop your accumulation.
You can enjoy your money from salary and use it to enjoy your life, increase your life quality and experience while you simply hold your accumulated bitcoins and let your Bitcoin portfolio works for you. I don't see anything is bad if you stop accumulating more bitcoins. It does not mean your belief in Bitcoin broken because of this accumulation pause or entire stop.
At the end people work for money, use money for investment in order to chase wealth and better life quality. They don't invest for example in Bitcoin, to die with bitcoin while their life is lack of things that can make their life comfortable and high quality.
