in 2013, the bitcoin condition that affected the value of bitcoin was very good, Germany legalized bitcoin and considered "private money", zipzap services increased the volume of bitcoin for 2014, 12000 restaurants in US received transactions using bitcoin, and ebay also received services for bitcoin transactions.
and that is a positive condition that can make bitcoin have a higher value, and in reality, bitcoin creates graphics better than in 2012.
and today, we see that many positive conditions, but do not affect bitcoin to create bullish, what happens with bitcoin?
In 2013 Bitcoins was limited to certain countries it wasn't global till 2016 end where it suddenly shot up in all countries. If you say 2013 you need to remember Mt Gox event also took place then, at least we have seen nothing like that now, also it's pertinent to note there was little or no fud back then, but now each and every media, government and big business owners have made a habit of spreading fud and bashing bitcoins hence the downfall. However soon all this will fade and bitcoins shall rise once again.
