Offer crypto holders chance to be part of new crypto startups (people who made money through crypto want to pay forward to the crypto ecosystem) and fiscally disadvantaged/ sustainability people/ project (WSB ape story) without requiring them to sell their cryptos.
Edit: Also, I don't have all the answers, if I did, I would be executing the idea instead of talking about it on a forum. My reason to share is two folds:
1. I am aware of several crypto-lending startups prior to BlockFi that failed. BlockFi founders are geniuses to figure out a structure that works beautifully. By sharing, I am just exploring where else the similar structure could potentially work.
2. Sharing such ideas exposes me to potentially complementary-minded people who might have answers, I may not have, and explore pros and cons that I may not have considered. You never know who comes along in future endeavors.
2. Equity crowdfunding is a way around 1. but only too restrictive- limited fundraising, more disclosure, and follow-on venture/ traditional funding hard to come by.
Above is US-centric view. Using crypto instead of fiat currency is not a workaround regulations and reputation.
But look at BlockFi, it might offer you insight into workaround using crypto to raise an Angel/VC fund from crypto millionaires.
