Below are some actions which are desired/possible to happen before announcing the IBO.

• Announcing a public testnet.
• Talking to potential exchanges (after announcing the testnet).
• Improving the website and documentation (maybe writing a whitepaper substitute).
• Waiting until Tendermint is production ready. Speaking of that, there are only 4 open issues left in the “launch” milestone (with 42 closed).

Sorry - meant to read 740,000, typo.

The block target is 64 seconds.

60 / 64 x 1.5 = 1.40625 generated per minute
x 60 = 84.375 per hour
x 24 = 2025 per day
x 365.25 (taking into account leap years) = 739,631.25 per year.

Current supply: 76,603,031 BLK

100,000,000 - 76,603,031 / 739,631.25 = 31.633288885508826 years to reach 100m coins.

There’s no hard limit but the inflation is fixed at around 840,000 coins a year. So while we’re at 76 million coins today, it will take until around the year 2050 to reach 100 million.
