If someone want to make money over internet then he should have some sort of service to offer then people will hire you and pay for your work or service.Nothing in this world is going for free to earn,need some sort of effort.More your skills then your earnings will be more.Everyone is going to say join the signature campaign and earn some bitcoins so I am also suggesting the same but your need to be a good quality poster and new merit system is going to be tough for the new comers.So you can join on altcoin bounties that also give good earnings.

No chance we will ever see bitcoin as international currency - LoL. But we will one day for sure see some other cryptocurrency as the main international currency. Unfortunately, I am afraid this will happen only the day that the banking system will have found a way to be in control of that 100%. I hope I'm wrong though.

It will takes time that bitcoin will be our international currency,it is a long process and I guess many people will hinder on this but i think bitcoins has a big chance and I can say that if that happens the crypto users will surely happy on it and many investors will surely invest on it and the btc will higher on its price.

it all depends on whether the Goverment will be able to adopt it at the legislative level, in some countries it is tough, in some there is not, I think it takes time
