A good explanation has been done by the OP itself..

Here is what i think are the key Factors to watch for Post-Launch Performance:

• Since the basic idea of ALEO's mainnet launch is to attract developers than monitoring the size of the developer community will be important.
• It wants to facilitate the creation of dApps - so how many are being developed will be a key factor as well.
• The introduction of a token - how the market will accept and react to it.

Overall keeping an eye on these milestones and factors will help you assess ALEO’s potential as it develops post-launch.
