Many dApps are competitive.
How about introducing a system monthly that incentivizes the 10 DApps with the highest transactions?
This not only helps attract talented dApps, but also provides funding for promising dApps to develop further.
For example, from 1st to 10th 10000icx~1000icx It costs roughly 40,000 icx per month.
for monthly expenses I think that excellent dApps develop further and contribute more. It is also an indirect marketing that attracts developers and users.
However, the problem is how the fund are made.
