My suggestion is Iot Chain (ITC). My reasoning is as follows:

• ITC has been dubbed the 'IOTA of China', due to being one of the forerunners in IoT development
• ITC is the first crypto (afaik) to deal with the pressing issue of security within the Internet of Things
• ITC has been listed on CoinMarketCap for only 1 month, yet already commands a market cap of $180m
• Their yellow paper, white paper, and test net will all be published in the next few weeks - this should be the major catalyst for ITC growth
