I think the biggest problem is the price of bitcoin that always changed. It's not good for people who work on bitcoins and get salary with bitcoin,
I think this is not a big problem. but indeed bitcoin price fluctuations, because if stable will be boring and it is a great advantage of changes in the price of bitcoin.
Well Safari88,i like that you have found stable price on any asset "boring"
It is probably because of bitcoin,this currency is just so fast and has such a great price fluctuations,that everybody who is in the phenomenon of bitcoin,will
be bored by other currencies or assets,because they are safe,slow which may mean also "boring"
anyone volatility attracts small players,and safe ( stable price of an asset ) attracts big whales.
