In my opinion, you don't need to understand the deep technicalities of bitcoin to be able to be bullish on bitcoin. There are a lot of big names in the community like probably Saifedean Ammous(author of The Bitcoin Standard) and Tim Draper(quite a famous investor) that understands what Bitcoin can do and what it's trying to solve, but not necessarily understand the technical stuff.

Also, if you don't have that much money to "invest", you can always go slow. You save $50 a week? Then put in $5 a week. As time goes, that will slowly but surely accumulate.

And lastly, if you have any questions that you don't understand, you can freely ask here. Just make sure that you don't answer very simple questions like "how to make a wallet" that could be easily Google-able.
