Is it possible for a potential investor (without funds but with a good idea and a great proposal for investors), to pitch a Bitcoin investment idea to a group of friends and family and companies, with projections of good profit but with their invested funds, to gain backings?
The underlined word is "to pitch a Bitcoin investment idea";
It's possible , but you must have solid investment plan and have unique selling point that makes you different with other crypto asset management companies . Perhaps you're very good in short term investment and have good track record ? something like that .
Since you mentioned is a Bitcoin investment idea , are you planning to invest solely in bitcoin ? I suggest diversifying as it plays a crucial role in the risk management of a crypto portfolio. Allocating investments among different cryptocurrencies and types of assets allows investors to diminish the effects of underperformance in any single investment.
Anyway is quite risky offering investment opportunities to close friend of family , but if you want to do it , you need to be professional and don't forget the paperwork .
