Bitcoin with its direct usage has eliminated the intermediaries who commission big out from each and every transaction. This has made a big loss to the banking and other service renders. Upon this people used to term it damaging to the economy, but it directly benefits the user in terms of economic growth. This way I believe it has got practical use same as fiat, but it hasn't reached upto the level.
Bitcoin was created with the aim of creating practicality in conducting transactions between users, namely peer to peer. Indeed, for implementation it must use the internet and Android phones or computer devices which are integrated transactions. This is not practical, but with the increasing number of Android phone users I don't think it's a problem.
The most important thing is education about using bitcoin and understanding the rules that accompany it, because each country is different in its application.
