I agree with you, actually the main factors that determines every successful business is planning, however that's why they said "he who fails to plan, plans to fail", planing is very essential that without it a business could fail.
One of the major factor behind every investment failure is improper planning, because is not possible for someone to just wake up one morning and decided to invest on Bitcoin without putting something in consideration such as knowing the potential of your investment, having a diversified source in case others did not work, knowing the risk and how to avert it and most importantly always having a reserve funds.
Planning is main factors how to be success when investing in bitcoin but don't forget with another important way about hard decision keep accumulate and investing in bitcoin what ever condition of bitcoin although in lower price. Many investor have good road map or planning for investing in bitcoin but many of them afraid when getting moment bitcoin in lower price but not braveness for put their money in bitcoin. There are not important with how your planning have been schedule for long time but you not brave for accumulating bitcoin as how many possible.
Good planning, brave for taking action its most important if want to be success in bitcoin investment, based on my way although still not success yet but with 100$ accumulate every month seems promising for few years later to earn much profit with bitcoin investment.
