Quick => is not a quality time on the market.
That's why we should adopt patient and cold approach to both trading and proper hodling.
So the right behaviour would lead to the right results.
Usually buying Bitcoin depends on how long you hold your Bitcoin, if you are holding Bitcoin for a long time then of course you can hold Bitcoin in any situation. And if you are holding Bitcoin for a small number of days then of course you have to buy Bitcoin in your thinking and cold situation. So an ideal investor will buy Bitcoin according to such a plan as to how long he will keep his Bitcoin, but I think holding Bitcoin for a long time is the most suitable and the risk is low.
You can invest in Bitcoin in any situation if your investment is long-term, because the chances of achieving success in long-term investment are highest.
I agree with you, actually the type of purchase depends on the investor's perspective. Every moment is the best time to invest for long-term holding, so if you invest for long-term purposes, there is no need to worry about the price, because even if Bitcoin dumps in the short term, Bitcoin will definitely pump in the long term. Those who can patiently build a strong portfolio of Bitcoin and hold it for a long time, they will definitely be able to profit a lot at some point.
But a short-term investment can never be safe, because due to the short-term volatility of the market, an investor will easily panic, and sell at the wrong time and face losses. They think before investing in such a way, "It is very easy to make money this way", but when they face reality, they face real losses.
So before investing, decide how much risk you are able to take, and keep investing using the right strategy according to your ability. However, the best strategy is long-term holding, because only long-term holding has the highest potential for this profit.
