To be a part of the growing digital currency network, people need to use bitcoin. Bitcoin usage will increase, once more people become a part of the grown network.

I think there is many reasons for that: relatively private currency, you own it, it isn’t inflationary, sending money internationally with low fees.. and many many more reasons why should people use bitcoin. For me bitcoin is great opportunity for everyone to earn and learn something. Of course still there is a lot of suspicious people, but that will change one day. And that day is closer and closer.

Every user of bitcoin tries direct payment with bitcoin when they get the chance to pay for their desired product or services.

Quick and easy, simple as that.

Bitcoin is semi-anonymous. If you purchase Bitcoins from an exchange and use it to send money to a person anywhere in the world, then basically the exchange can follow every step closely. It's bad because governments may/can force that exchange to release all information about you. That's why I mix my coins directly. Full anonymity is still not guaranteed, but it will reduce the chances of them finding your transactions much much smaller.

Because it's much easier to use bitcoin rather than paypal or any other payment method, you don't need to send ID. bill, bank verification or phone number etc. With bitcoin everyone can easy start making transaction, which are little delayed comparing with paypal which are instant.

Really bitcoin looks to be one among the greatest innovation of human creation. Fiat is much important but at the same time if bitcoin grow enormous and gets to 50% of usage, gradually fiat users will start following bitcoin.

Need to keep up with the times, this bitcoin money of the future!

50% is too huge to expect mate, and which seems to be impossible too, even if 20% of entire population starts using bitcoin in future then we can see bitcoin achieving many milestones in future.

Because with BTC you dont need banks.
You are your own bank.
