Hi there, if starting university affects your passive income, it matters. That being said, what you're currently doing is ok. However, if starting university does not affect your passive income, then you have a lot of thinking and planning to do. You have $300 in ETF and investing in this and robo advisors are kind of like the same category (in my honest opinion). The balance of money should be diversified with the following considerations: 1) risk appetite: lower risk stuff from bank deposits (1%p.a. onwards) and insurance savings (3%p.a. to 4%p.a.) to higher risk stuff from shares (which gives passive income in the form of dividends) to speculative trading (sky's the limit but you need time and skill) 2) time horizon: how many years are you able to lock up your money when they are left in investments? I hope you do know that investing in ETFs will need about 5 years to see significant returns. Bank deposits and savings have short time horizon (a few months or almost instant liquidity), shares and etc have mid term horizon (people may hold positions for weeks to months, up to a year in trading, or for longer periods if they're keeping it for passive returns). Insurance savings have longest time horizon, 10 years onwards. 3) what are your goals - you don't only have one goal so you should split the pot strategically to reach your goals. Some goals need more time and are more important and will need something more stable. Other goals may have shorter deadlines but you can be more aggressive 4) is there a way to increase your side income? If you took little effort to get $1k monthly, is it scalable? If it's scalable why not use your side income to generate more side income? Lastly, as for the $15k savings, I'd suggest leaving it alone for emergency use. If you already have emergency fund set aside, perhaps putting the money into any one or more of the above mentioned instruments can be done.
