I myself became very skeptical of many ICO because of the scam, And people can do nothing with it

I think altocoins are good for the technology to improve and new use cases for blockchain.

You got that one right we have 2018 coming developers will give us a lot of profit with our coins been holding in our wallets we just have to wait and see what happens

paper money will always exist,it never have ending,you know so many countries use paper money for payment.
but i also believe that sometime paper money will not popular again,but it just on a big country like US,and never end in small country

Generally yes. Many new ico starts every day. But it is really hard to understand which is a valuable project. Therefore, it is necessary to carry out a thorough research and invest accordingly.

Its definitely one of the best methods to invest because usually, the price doesn't go under the ICO price when the campaign ends. This depend on different factors though, If there is a lot of bounty, a lot of people will dump them because they gained them using easy work but as a general rule, as long as the ICO has a solid team and a realistic goal to reach within a known period of time, you should go for it.
