Bitcoin was not made to spend. Not for now. There is a misinterpretation of what Satoshi wrote in the Whitepaper: "A peer-to-peer eletronic cash system". He created bitcoin to be an electronic money system. This is a fact.
Before becoming a monetary system, Bitcoin must be able to preserve value over time. After that, he becomes able to earn society's trust and become a genuine cash.
Okay, Mr. know how, I think that what you think you know about satoshi abstract is wrong, probably you mis-interpreted it because if we don't spend bitcoin, how would the law of demand and supply take place to make bitcoin value grow.
I believe you know that the more you spend bitcoin, the more you tend to make demand for it, which it is when demand is higher than supply that bitcoin would be able to grow in value, and before you even advise people, one of the reason why bitcoin is still not getting much of adoption is because people are practicing exactly what you said here, they are just holding their coins for investment purpose only without actually spending it and you can see why bitcoin is just fluctuating, without spending bitcoin, the volatility will never reduce.
