The idea on investment is such that people can easily put their money in. They want to get as many investors as possible and mot many people are still into bitcoin, it's a fact whether you choose to accept it or not. And I see that becoming a reason why investment is still in dollars. If you accept only bitcoin and I have tons and tons of dollars to invest, do you really want to turn me away? that is a big question mark.
Personally, I hope to not ever be in a position where I desperately need someone's money when raising capital as that would put me in a bad negotiation position. Assuming I'm not in that position, I'd ask you to acquire BTC and would be prepared to lose you. I'd respectfully say,
"I'm running a Bitcoin company, and its existence depends on Bitcoin itself becoming more widely adopted, not just in the small realms, but in the big ones, too. If we can't get investors to invest in Bitcoin, then I worry for the future of Bitcoin. I don't want to perpetuate this cycle and want to set a precedent to only accept Bitcoin. And, I hope if I do this today, then others will follow in my footsteps. This will be good for Bitcoin, and this will be good for my company. I can refer you to various trusted parties where you can acquire Bitcoins and would be happy to accept your investment, kind sir. If not, thanks for your time" Well, I'm a stubborn mofo, I told you.
I guess I understand what the reasons are for not seeing capital raised in BTC in practice - volatility, potential laws for accredited investors, flexibility, etc - but the first legit company that requires BTC investment will garnish outmost respect not just from me but from the community as a whole. How do we get there? When will we get there? I think if Bitcoin is here for the long term, it's only a matter of time. The question who will be the first?
