Everyone is the target market. Everyone who hates centralized banking or the banking industry in general, or maybe even their government to a smaller extent. Bitcoin benefits almost everyone on earth simply because it allows you to remove the middlemen that siphon money out of your bank accounts for random bullshit(like wells fargo or BoA for instance.) There's no central point that can be corrupted, so it's just a system that will exist until everyone stops using it. There's no 'bitcoin network failing' either, it's a nearly flawless service. The biggest issue is the price for transactions, but there are other coins with lower fees that people will start using when it comes to smaller transactions. Bitcoin is great for everyone.
