Crypto wallets

I want to pick an open-source replacement for Coinbase, Binance (holding and sending cryptocurrency). Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - Sparrow Wallet: Sparrow is a desktop program for managing Bitcoin, a digital currency, that works with many hardware wallets (physical devices that keep the keys safe). It is meant for people who want to hold and send their own bitcoin with more control and transparency. [Easy setup; Windows · Mac · Linux; replaces fully; Apache-2.0; https://github.com/sparrowwallet/sparrow] - Electrum: Electrum is a free program for holding and sending Bitcoin, a digital money, on your own computer or phone. It is aimed at people who want to control their own Bitcoin rather than leave it with a company. [Easy setup; Windows · Mac · Linux · Android; replaces partly; MIT; https://github.com/spesmilo/electrum] - Cake Wallet: Cake Wallet is a free app for storing and sending many kinds of cryptocurrency on your phone or computer, with the keys kept on your device. It is aimed at everyday people who want to manage their own crypto rather than leave it with a company. [Easy setup; Mac · Linux · Android · iPhone; replaces partly; MIT; https://github.com/cake-tech/cake_wallet] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/crypto.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/crypto.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
