Bitcoin is divisible. I made a purchase recently for a $6 item and the cost was .005₿. Bitcoin is easy to spend using gyft.com but better discounts if Amazon purchase is to use purse.io
Anyway, there is truth that bitcoin is worthless, literally pennies or less, but it has to do with time-perspective. To get bitcoin 7-8 years ago, one only had to visit a website and get 5 coins. You can run the mining software on a laptop and get hundreds of bitcoins a day, rewards were 50₿ every 10 minutes, and bitcoin network hash rate was very very low and bitcoin difficulty was very very low. If you had a graphics card, maybe you would have had thousands of bitcoin in a few days. Many people with passing interest have seen the article of the 10,000₿ pizza purchase (worth 12.5M USD currently) or the $18 purchase of 5,000₿ that was cashed out to buy a house when it was worth $700,000, now currently worth $6M
So, this is where time screws us all. Today, if you spent $10,000 on specialized hardware (ASIC's) that can produce trillions of hashes per second, it is very unlikely you will produce even 1 bitcoin in 24 hours (reward is actually 12.5₿ for the miner plus transaction fees collected from people who make transfers). It's based on probabilities so it's not impossible, but the chances are extremely slim. Bitcoin network hash is very very high now and the bitcoin difficulty is astronomical. The amount of miners with China having some of the most powerful mining farms costing millions of $ in hardware are the competition. Many miners join mining pools to combine their hardware capabilities. Then there's the amount of power/electricity that is spent for all this mining effort and the heat produced.
There is no other way to create a bitcoin other than to mine it. Mining is more costly than straight purchase even at $1,265/₿. That is my simple attempt at explaining why a bitcoin costs more than gold, currently. It is more costly to mine bitcoin than it is to mine gold.
In addition, bitcoin can be spent very easily, electronics, food, travel, or even a house, unlike gold...
