2017 is a up and down year, you can not start to use altcoins in a real business, to much volatility, maybe 2018 will be similar. Crypto has a long way to go. I will wait until the time will come to implement a coin to my business. For Eth and Bitcoin it is to late to dream big profits, it is posible but you need to risk a lot to win, i will go with cheap coins. Steem is a great coin for 2017, i am sure will go 6 to 10 $.
