When the internet was first came out there was a lot of big discussion about it. Its rubbish, it'll never work, its brilliant its going to change everything, its just a fad etc. Then one day we all started using it like it had been there all our lives. And now we can't imagine living without it.
Bitcoin and blockchain is seems to be following the same route. There's so much big discussion about cryptocurrencies but with scaling issues looking light they might be solved (with some currencies) and new blockchain platforms coming into the market could it be as early as next year when the big discussions cease and we all use the technology likes its always been there?
Today I bought something in a London market and said to the store holder you should take bitcoin and she said, 'yes it could be the future of money'. Then I bumped into someone I know and they said exactly the same thing after I mentioned something about bitcoin. This is a significant change in tone because even 4 months ago people usually said, its scam, its a bubble, be careful, I wouldn't invest in that etc.
That's exactly what happens when something ahead of its time gets introduced in the market. People thinks it is rubbish, then starts looking into it because others are doing it and then they finally accepts it. That's the normal acceptability graph of any new thing, be it a technology or any revolutionary product.
I want to cite a very famous quote by the most respectable freedom fighter of India, Mahatma Gandhi here. He said, "First they ignore you, then they laugh at you, then they fight you and then you win". Blockchain technology is going through this particular phase at this moment. Banks around the world understand that fact that blockchain is the future in financial transactions, but since it posses a significant risk to their business, they are fighting against it and pressurizing the governments not to adopt it.
I am sure, one day will come, when only blockahin technology will be used for any financial transaction. It won't happen within a year or two, but gradually it will happen over next 10-15 years.
