Option B would be the most realistic and the one that makes most sense to me
I'm not sure if they're nonsense or not
They're neither. They are non-committal, short term, and neither explicitly consultant nor employee nor company executive.
It is very unclear what you want.
Do you really really really want to own a business?
If so why?
Good luck.
Hi! I am also starting a tech consulting company, focusing more on blockchain as of now. Depends exactly if you want to grow as a consultant for firms or start your own business. I would advise with option B if you do not think you have a strong enough network to be able to get clients since its ~70% of the business. Go with option B, build a strong network and potential client list, exit and start your own company. I also would be down to chat if you like.
