Some people make the mistake of selling all there Bitcoin just because they want to start a new business or investment with the money and after selling it and the start there new business or investment some time later it crashes and they lose it and also lose their bitcoin investment so keep your Bitcoin investment going while trying out other business or investment.
Selling our holdings at once is never a good practice, I'm sure that Majority of this people that like selling all there bitcoin are those Investors that have not accumulate enough stash of bitcoin in thier portfolio they feel that after selling it that it won't take long to accumulate it back. While those Investors that have been struggling to reach the status of overaccumulation can only sell 5 to 10% of thier holdings whenever it double and after that will have to allow it to compound upon itself before attempting to sell again, because they know how Long it takes before they were able to reach the status of overaccumulation so they wouldn't want a situation where they will start the accumulation process all over again.
Many times it is seen that there is everything to invest or do business, but due to the right planning and mindset, both the investment and the business are ruined. Starting a new business is not bad, but selling Bitcoin should not be done for all businesses. One thing to understand very well is that holding Bitcoin for a long time will not make anyone reach the overaccumulation stage, which is not true. Many times, due to income uncertainty and poor financial planning, many cannot reach there. Therefore, selling 5% to 10% is only logical when that level can really be reached. Therefore, the right planning and mindset make the difference between success and failure.
It seems you look a bit confused here in your explanation or am I not getting it right, because if you have a good plan or minds in your business and investment, it can't be ruined , it only gets ruined when necessary plans and measures are not put in place or you don't even really understand what you are going into and starting a new business with no direction will be the biggest mistake you would have made because you will achieve nothing
, and brining such idea into bitcoin by buying today and selling tomorrow tomorrow will lead your investment in bitcoin to nowhere but just crashing at the beginning of your Investment.
It is not advice able to sell off or part of your bitcoin for any type of business you are into instead, look for another source of income to grow your business, you can involve yourself in a daily pay job for just a short period of time just to balance your business up instead of selling part of your bitcoin investment 5%-10% in other to stabilize or setup you business, I bet you that earnings you received from that short period job can't be compared to selling 5%-10% of your income, it will be far lower than bitcoin, then why not keep hodl for long term than selling off. Remember bitcoin is a long term investment for 2-3 cycles or more not a short term used in solving monthly expenses .
To be successful in life, you need to be serious in whatever you do and anywhere you find yourself .
