none of the wallets/exchanges i'm on will show a easy to read list of your investments gains/losses that you'd typically see in a brokerage account. am i missing something or can one be created?
Try putting it in a spreadsheet. I do that and it's a great way to keep track of all your trades.
With "Spreadsheet", I obviously mean "Google Spreadsheets", which is user-friendly, available worldwide, free and has a ton of functions that make your life a lot easier.
You can just use a different column for each day and make a new tab for each month, which gives you a good overview. I also recommend backing it up somewhere. (I got multiple google accounts: a spambox account, a regular-use account, a back-up, etc.)
So instead of being served, you must serve yourself: Start making spreadsheets.. They're really useful!
