<prompt> Human: I have a regular cheapo Amex Blue Cash that I never use except for one very small recurring expense just to keep it active, and have been using a Chase Sapphire Preferred for the vast majority of my purchases. The 2 restraurants is what sold me on that.After the last CSP annual points dividend, I decided Id probably go ahead and cancel it and pick up a Fidelity Amex for the 2 on everything. Now, I knew that it went to a Fidelity investing account, which I am cool with, but dont really know anything about.Im looking to maximize the 2 back I get from this - so dont want to squander it all away on transaction fees for the funds and such...not really knowing about the account, it looks like theres roughly an 8 fee per transaction?I was imagining a situation where I could more or less use this care passively and have 2 deposited in to an account I could forget about for a few decades, and have a small bit of extra coin one day. Is this possible, or did is this just a fantasy that isnt what this product actually is?Possible relavent stats if necessary - late 20s, US Federal employee w maxed TSP, good emergency acct, etc.  <response>: You should be able to invest in Fidelity mutual funds with no loads or transaction fees.
