I recently got into investing at 21 years old. I opened a HYSA for emergency funds, and a ROTH IRA for retirement with Fidelity. Should I open a General Investing account with SPAXX? I plan on putting leftover money on there and invest in ETFs once i max out my ROTH IRA. Hopefully I’ll be able to put enough so that it can grow and pay for my travels. Is this a good plan?
