A business plan: A comprehensive business plan can help you identify potential obstacles and create a roadmap for success. Your plan should include a market analysis, financial projections, and a marketing strategy.
All of the things which you mentioned are really beneficial for those who wants to have a successful business. Actually planning before doing something is necessary because if you don't have any idea that how you will manage it and what will be your fortune by doing such business then it's not an easy thing to get the desired result. Putting money is not easy in some business without planning and knowledge because there is a greater risk associated with it.
A team: You may need to hire employees, contractors, or consultants to help you run your business. Make sure you have a plan for finding and retaining the best talent.
While talking about the teams so I think that if a person is doing an online business then there is no need of having an employ or helper but in the case of investment you have to gather information related to coin but it also don't have any need of employ so you can easily get the idea from YouTube and groups.
