I feel this depends on how well adopted bitcoins become. At the moment, I don't think bitcoins can reach mass adoption like credit cards because of problems with blockchain size, and TPS limit. Also, Frankly, and sadly, I just feel the average person can't be hassled to deal with bitcoins. People can't even take control of their health, day to day finances, and debts and now you expect people to safely secure their bitcoins, spend time getting verified, moving money and buying bitcoins? If there's one thing that credit card company's did right is they made it easy for people (at least in comparison to bitcoins or cash) to secure and transfer their money, while at the same time extending credit. Lose your CC? call the company they can get it deactivated. identity theft? most companies will refund. Need points, cashbacks, rewards, Cash withdrawal around the globe? we got you. Heck I don't even bother with cash most of the time unless I'm going to chinatown (those guys are always cash only, maybe bitcoins would work for them?)  because the convenience of using a credit card is just that much higher

The other argument is over anonymity. In most cases anonymity is pretty overrated. While I want my purchases and transactions to be private, I also don't want my money to not be under my name or traceable when stolen. Just like you wouldn't keep thousands off dollars in cash under your mattress, but instead rather have the bank hold it in your name, where consumer protection laws can help a great deal to alleviate any crises, you wouldn't want to keep thousands of dollars in such a manner where they can't be effectively traced back to you.

Ultimately, even though I love bitcoins, I wouldn't see myself using it to buy items which break easily, such as electronics, or for large purchases, like airplane tickets, cars, electronics, nice dinners etc. using a card gives me more flexibility, rewards, and consumer protection. 2.5% is a small fee to pay to get all these advantages ( I pay everything with credit card and just pay it cash at the end of the month, the benefits are just too good to pass up).

The other argument is over anonymity. In most cases anonymity is pretty overrated. While I want my purchases and transactions to be private, I also don't want my money to not be under my name or traceable when stolen. Just like you wouldn't keep thousands off dollars in cash under your mattress, but instead rather have the bank hold it in your name, having tons of bit coins, whether in an offline wallet or otherwise, leaves it with little way of connecting the bitcoins to you.


I guess what I mean to say is, bit coins, and its current state, just isn't scaleable and as convenient to use as other forms of purchasing.

So what do I think bitcoins are good for? I think bit coins is good for large transactions or transactions where anonymity is crucial or transactions where being able to dispute payment is high. Of course instead of trusting your credit card company to handle in any issue, one of the persons in the transaction would have to go first , so trust is not in a large organization which can have tons of reputation on the line.  

Overall. Bit coin is a currency that fits a very  specific niche and is, as many have already said, and experiment, one that has highlighted how dated and cumbersome banking currently is. Hopefully, banks around the world find a way to standardize transfers and make the available 24/7 within the next 10-20 years. If banking systems cannot catch up to the current globalized 24/7 high paced, instant communication world we live, then maybe, maybe do I see bitcoins becoming worth 1000$+
