The scammer of ICOs given a wrong point to puclic that the Blockchain is a great thing it has Great Applications , but low profit on cryptocurrencies.
Nowdays , people think cryptocurrencies might be useless, but blockchain-tech has great expectation to change our world, and it has much applications in many industries.
In fact, the blockchain-tech is not. excepted the cryptocurrency, less use in any industry, and this tech was expensive, slow, bad experence. In payment industry, such like Alipay ,Wechat , Paypal , the traditional tech they use is better experence than blockchain.
Otherwise, the CryptoCurrency which based on the tech of Blockchain is the Great one. The CryptoCurrency is given the Seigniorage to the People from government. If the Seigniorageis not reserved to the state, so the government can not robbery your wealth.
That will really change the world in future, the seigniorage to the people , the government has no fund to make war.
Some times we asked what is the applications the AB you issued. we said it is no application , it is just a kind of currency , it can be Useless on any Applications. Just like USD note, you can't package a gift because it is to small , and you can't cut the fruit because it made in paper. It is just a note ,a currency , can be useless.
