At this moment, i still not really sure about another coins beside Ethereum and Bitcoin.
Those two are irreplaceable choice, in therm of favorite coin. But if i had to choose, then i will choose Waves.
I think this is the best 2 coins in which you can safely invest , I would certainly be afraid to invest all your money in other altcoins , I'm in the Ethereum quiet , but if you think so then I would choose would be eos
Bitcoin and ethereum are the best coins at the moment, with a very good level of investment, we can avoid the bad risks that might occur. for other coins, I'm not so sure, so don't ever use our money to buy just one coin. vary the investment that we have and have more than 5 coins can be a good stratgey. our job is to get good momentum, when the right situation occurs, then immediately make decisions quickly.
