If you will try to deliver pizza on them, your business will fail obviously. But are those trucks a failure? No.
My point is that today's Bitcoin can be compared to those powerful trucks in a sense that it is a very good tool for massive, over $1,000, transactions, especially when they are transnational ones.
You make a great point there. Right now Bitcoin is used by institutions storing or transfering huge amounts of value. Also it is used even more for speculation. Most people and institutions that own Bitcoin prefer not to spent it, but instead hold it in their hardware wallet and have it probably buried in their backyard.
We talk about pizza day and every single time we have to count the Bitcoin's spent in today's dollar value. Everyone is actually claiming that you should not use Bitcoin but store it instead. From my point of view Bitcoin is not store of value. It is not a piece of art that will be sold at an auction.
The purpose of any currency is transfer of value for exchange of goods. In the case of Bitcoin it is digital money. Bitcoin is obviously deflationary, meaning prices of goods become cheaper in time as they cost less and less Bitcoins. So people think they should store it instead of spenting it. This is not adoption though. This is just speculation. Without people using Bitcoin we cannot see a major shift in public view in favour of us. For real adoption to happen we need to be able to buy a cup of coffee with bitcoin, without paying double its price and waiting in que for the transaction to confirm.
I have high hopes that we have a few of the best developers working for this. Otherwise I would have just kept speculating about price and not even caring.
