If bitcoin don't go $100k in a year or two... What can you possibly lose? From here, your worst scenario is $5k. At worst you'll lose half of your money. I know it is not pennies if you go all in. That's why, you need to DCA. (spread your buys over months, weeks)

Even if you still find that $100k a too crazy number...

Just tell me what are your other options for getting rich?

Gold? Must be a joke.
FIAT? Dead.
Stocks? Already in a bubble if you get in now, you won't be sleeping at nights.
Real Estate? You need to be rich beforehand which is a dumb idea to begin with
Altcoins? Might be an option but I wouldn't advise that shit. Most of them are scam.

Don't get me wrong, I use Bitcoin to store my wealth outside of the banks and It serves that purpose very well, I am just after that side benefit; "getting rich" while doing so.

If you don't  fully understand what bitcoin is and what it can do before investing in it, you won't be able to hodl through. As soon as you see a small red candle, your mind will give you a blue screen and you'll panic dump. That's the same mindset which kept me from investing in btc for years, I know.
