For the desktop I am suing the cli wallet. I like the command line. For the cellphone I will go with your recommendations and try cake wallet.

on desktop i use cake wallet too. I have monero gui, but, how i have others coin, like nano, bitcoin, solana and monero, cake wallet work wll. to help monero, i use XMRIG, to miner.

I am a Monero maximalist 😜 Nah... I am just joking. I really want to play with smart contracts. But one step at a time. First cover the Monero use cases. I am afraid of the resource consumption of mining and of a full node (which you need for mining). I will have to get a new SSD or Nvme drive for a full node and a way to limit the resource consumption of the miner (maybe run it in a VM with a fixed amount of cores?). One step at a time. Let's get the basic use case (using it as money) under way and then go to advanced mode.
