bitcoin difficult to understand because the bitcoin coin is first digital currency and most probably human not understand .and if you really want to know so go on youtube ....there have more videos of bitcoin.
A good opinion and I like your opinion.
Actually we have to rethink about bitcoin because bitcoin will be hard to understand if we are less familiar with the meaning of bitcoin and less deeper bitcoin way so we find it difficult to understand but if we really know and understand about bitcoin then I am sure anyone will love bitcoin with pleasure.
