I am creating my crypto project from scratch.
My friend and I are crypto enthusiasts. And we want to do our bit to the community. So far, it was in our power to make only a news aggregator, but we are actively working to expand its functionality.
We want to make some useful tools. For example, I personally did not find a convenient portfolio for myself, so we plan to add these things to the site.
Also, we have the idea of a tool for comparing currencies on exchanges. We want to make a convenient place where all the tools you need are collected in one place. And in the end, we plan to make a convenient and practical toolbox out of just a news aggregator.

What tools do you use to interact with cryptocurrency? What functions do you need? What do you advise us to strive for?
