There are so many altcoins with lot of features and different type of usage, some of them are fake and some of are very good.
What coin do you think technically the best among them? (Don't just judge by the popularity or by the market price. )
Eth is the safest altcoin for investment, safe doesn't mean that it is profitable. I know a coin called XCPO which is masternode coin, it is profitable because it gives passive income everyday but it isn't safe. If it's developers are gone then this coin wipl not has any price. But fortunately its developers are honest people, they keep take care of their coin by creating an e-commerce marketplace that use XCPO because it is their main one source of income. They work for themselves and their invester.
