Thanks for your question.
My priorities would be:
1. Invest in yourself — read, learn, watch — do so purposefully.
2. Longer-term (maybe slightly higher risk) investment vehicles are what I would focus on: equities, real estate etc Particularly using REITs, mutual funds — as they provide you appropriate risk mitigation through diversification (index especially) etc. As a younger first-time investor you’re after growth — as you’ve time to recover any loses or compound your gains.
3. Personally, I’d stay way from more “speculative” items such as Block-china, derivatives, synthetics etc. They require more particular expertise that you can (or seek to) gain over time, but as a first-timer, stay on more “boring” stuff while you learn
