What is your opinion about IDEX?

You saw how the course took off after the news that at the conference, it is on January 18, they will possible present the testnet of their project. As many in reports predict bullish growth. How much are you optimistic about this coin? I probably will buy more....

Tell me please, where do you keep many different coins, if not on the exchange. Maybe someone knows a good solution. Since the Ether purse, Waves purse are not suitable for all types of coins. The number of my coins is growing and I do not want to open many different purses. Can there be a universal solution that I do not know about?

1969568.28324 / 6460600 = 30.5%
Since (1) is based on the top 100 addresses and one person can own multiple addresses, there are some extremely rich people out there.
It cannot be good for ~100 people to own 30% of all Bitcoin...
P.S. I'm pretty new at Bitcoin, so please correct me if my math is wrong or I'm mis-understanding something.

Russia and China I can understand.  But the U.S. is #7.
My friend lives in Sweden. He is interested in bitcoin.
Any ideas?
