I would suggest using a site called BTCpop (https://btcpop.co/). This site offers peer-to-peer lending where you can raise capital through either business loans where you pay off in monthly increments; much like a traditional loan you receive from a bank; or by offering bonds where you can pay back a percentage of the raised capital amount over time, using a payment structure that you design and is approved by investors. If you already have a corporation or are thinking about starting a decentralized exchange to sell your coin, you can create an IPO (company) within BTCpop and sell shares of the company as you would with more traditional financial institutions such as the New York Stock exchange. You can also try Nexo, (https://www.nexo.io/) and CoinLoan (https://coinloan.io/) these sites are closer to a traditional loan one would receive from a bank, but with lower interest rates and no credit check. I also believe the overall required collateral to qualify for the proposed amount on these sites is higher than BTCpop, and have less flexibility.
