Blockchain will disrupt these industries Banking and Payments, Insurance, Voting, Forecasting, Government, Crowdfunding, Retail, and Real Estate. Yes, we knew this that blockchain will play a big role in the future of those industries and it's a revolutionary.
But, do we need lots of cryptocurrencies?
More and more companies or startup companies were developing their own cryptocurrencies and a lot more in the future but what's the point of creating or developing it? Maybe we only need 1 for every industry but why does almost everyone develop their own cryptocurrency?
Realistically no, we don't. But if you think about it, those cryptos most likely end up being a scam or a fail,so those don't affect many things. The idea of using crypto to raise funds wasn't a bad idea until 2017 happened. People initially came up wonderful ideas, it just lacked proper implementation or some other key factor, and before you knew it: ICO industry became a joke. That's the take of most bitcoin enthusiasts.
