It's simple to create a dashboard for crypto, i just made the frontend for it, well a basic one and if i put a few more hours in i could do it on Node and make it actualy work as far as monitoring a portfolio goes. Any real transaction would take longer to setup as there are requirements like you need like a node.
Here is the Code to the basic dashboard i made, it's more so a design atm.

New Crypto users beware of scams as it isn't that hard to set up a dummy website if you know the front end syntax.
