It takes 40 years to mine the last #Bitcoin. This means if you are a whole coiner your children or grandchildren (if they smart) will inherit the equivalent of 40 years’ worth of energy used to secure the #Bitcoin network. NO ONE is prepared for this. 
Discussion
In your mind, how does this play out if the cost of energy drops to near 0?
Either by dramatic increase in supply, or dramatic decrease in demand for hash power?
Absolutely NO ONE can imagine…
Gud take
It really put it in perspective how little time that block subsidy is more than a bitcoin and that window is closing quickly, I think once block subsidy is less than a bitcoin things will get very interesting.
