Don't think that people on this forum are against business opportunities and don't want to make money, but everything you've presented is not enough to convince someone to just send you $5000 in cryptocurrency, after which nothing prevents you from disappearing without a trace. I am personally surprised that after 5 years in business you expect to be able to find a business partner based on nice promises.

I think you need to find that money in another way, whether you borrow from parents, friends, relatives or take a bank loan - which is a far better option for you than having a partner who can turn against you at any time.
