In addition to ether and bitcoin, I think it is advisable to buy EOS (despite the controversial events taking place around project and the negative from the community). NEO-chinese ether will pop up as soon as China creates all the conditions for crypto-currencies, and everything is already going to this. China will be the first, and the West and all the other countries will be at the end. I also think it makes sense to buy storj, ontology, stellar, ada.
The fact is that in the entire history of the development of the cryptocurrency market, Chinese developers have really shown themselves to be very professional. But lately it has become very dangerous that almost 70% of the volume of Bitcoin is contoured by the Chinese miners. It seems to me that the monopolistic influence on cryptocurrency from China is very dangerous for the cryptocurrency market.
I prefer to suggest the IOTA as the main investment coins in addition to Bitcoin and Bitcoin. the large number of advances that continue to occur in these coins make the JOT generated more continuing progress more profitable investment with it.
