Still a long time to go before the last mining will be done. There are a lot of altcoins now in the market with some great features. In the mean time they will make some good progress and continue to carry the market.

I have been using Changelly for a long time and I have not suffered the consequences. If you don't want use any of the mentioned then you can try Bitfinex, as they have a good reputation.

There are several factors one needs to keep in mind before investing in an ICO. While this type of topic has been discussed several times, I would just suggest some key points anyway. They are: Business Model, Legitimate Development Team, Technology and Innovation, Community, Association with Other Companies etc.

The foolish predictions are laughable. There is no reason for a economic crash in 2019 but USA is going through a rough patch in the stock sector.

It is great to see that bitcoin has passed almost a decade. But the true identity of Satoshi Nakamoto is still unknown. But there are some interesting facts about Satoshi like, he owns 1 million bitcoin.

I dont know who controls what but bitcoin is a decentralized currency of which I am sure. Some people claim that even in bitcoin there are whales who control the bitcoin market but even if that is true, I dont think they are in total control due to the nature of bitcoin. And any altercation in bitcoin market invariably brings some degree of shifts in altcoin market no matter how much respective centralized body tries to prevent it

If a ICO shows new innovations and great technology and also doesn't seem like a scam it will get investors from all the world. The country of origin will not affect it in my opinion.

No developer can help you with your project in my opinion. As it is said earlier that waves token mantains its own integrated exchange platform. But just for absolute surety you can contact with them.

Does it matter who are in the list? They have all done a great work and we are just getting the benefit.

I don't think every nation will unanimously agree to one currency. Rather it is more likely that bitcoin will be established as one of few global methods of payment. There are few altcoins which could actually be of widespread use because they are just so good.
