What centralized application or system will be decentralized by the cryptocurrency. Lets consider an example , who want to decentralized something like News Channel.

Next big thing to decide is the block rewards and block reward time. This too factor plays very important role when you launch the cryptocurrency. Block Reward time will decide how early transactions will be confirmed , putting this value too small will increase the difficulty eventually cost of block generation will be very high and putting it too high will slow down the confirmation. A mid level good choice is required. The other aspects Block Reward is required so that community will support the network for your coin.Too much off block reward will reduce the value to zero often termed as dumping of coins , to high value will increase the difficulty again a mid level block reward value is required to launch the cryptocurency. Step 3 This is the most difficult and most important task to launch and ICO and collect some funds.  Effective marketing team is required to launch an ICO , which will ensure that message is spread to the community and all are interested to invest and take the coin forward. ICO funds are very important to ensure that future development happens and coin is well supported and listed on exchange.
