I don't know why people say bitcoin is gambling. Its not gambling. You are investing your money and time. You use your internet. So its not gambling dealing with it.
Yeah many people even including many bitcoiners are usually talk with me and sometimes they called bitcoin work as a gambling .
I don't know why they are saying like this because I never think about bitcoin in such a way that it is like gambling because here everything is clear and transparent and nothing is going with hidden work like we seeing in gambling ( win or loss depending upon chance of luck ) .
Here we are much safe with bitcoin than what another Fiat banking system we have in our practical life .
I think people don't know bitcoin very well and also those newcomers in bitcoin are saying it like a gambling Because they are re looking towards the bitcoin in these days with much fluctuations and seeing them to make investment bet at perfect time .
