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.
