to me the world trend about fiat currency is changing toward crypto currencies and specially toward bitcoin, so i think it is too good to earn bitcoin for future and it will be even good to earn it in future, there is nothing wrong and nothing doubt about this.
The same view I shared with you and if anyone who is sensitive about happenings around the world of Bitcoin, such as investments by banks, court cases, governments getting interested from different parts of the world will will know that Bitcoin is really going places and its here to stay with us despite all other threat from competitors coin or people trying to whither down the influence. So it actually worth it to hold it and earn it for the future which is also depends on individual definition of future...
