Since you do not seem to have a legal structure yet, you should start out the way any (tech) startup tackles seed financing.
You generally want to do this on multiple levels. In the seeding phase, you try to crowdfund a certain amount of shares of your soon-to-be-incorporated company. There are many crowdfunding platforms out there. Choosing will be a matter of finding a platform matching the type of your business/crypto currency. If you want to go a more humble way, you could always approach friends, family members for seed financing. After that, you move on to series A, B, C etc. of financing rounds raising higher amounts of capital.
Since you're trying to launch a crypto currency though, further funding could be achieved through an ICO (Initial Coin Offering). Nevertheless, higher risks are involved with ICO's. Furthermore, a newer phenomenon keeps popping up, called a pre-ICO. Pre-ICO's generally work the same way, but raise less capital but at an earlier stage in order to reduce risk for later ICO investors and provide funds earlier. However, risks involved in pre-ICO's can be even higher which is why such instruments should be planned with great care in order to not come across as scam and build trust and transparency in your venture.
Id be happy to analyze your situation further in a personal call when provided whith further information.
