Bitcoin run, young, hungry and a little naive

Hey, 21m and am increasingly open to the idea of building out a speculative side account on Robinhood with Bitcoin. I think this can help me smash the 100k goal of mine. Bitcoin, Meta, and Amazon currently seem VERY attractive to get in and hold 3+ years. To preface, I do have a main account through a different brokerage with 70k in the S&P 500, acting as the reliable engine I won't interrupt.

I could go out to bars or do other degenerate shit at my age but instead I want to drive DoorDash in every minute of my free time and shove 15k into Robinhood over the next few months. Give me 10k in Bitcoin and 5k in Meta 2028 calls. A plausible 2-3 year case, absolutely with downside potential, is for this 15k to 3x-4x. Worst case scenario I turn 23 and have some VOO shares. Will Bitcoin more than 4x?

If Bitcoin follows it's 3 year pattern once again (50%+ drop, don't hear about it as much... then slowly ramps up before going parabolic as more and more get FOMO, taking it to new highs). At the same time, Meta is trading at a forward PE of only 17?! Like what... watch as sentiment on their AI spending changes slightly and their forward PE shoots to 25. I see very little downside there, the cash flow machine of a business is very unlikely to trade more cheaply than this.

Thoughts on these positions? A more speculative account at a young age? I feel like over 500k by 30 does not seem very difficult... Bitcoin could become the primary engine ????
