I'm all about trying to find coins that are still relatively under the radar, have tech I believe in, and can potentially net me a big return in the long run. One gem I'm betting big on that meets these criteria is Spectrecoin, Xspec. Its a POS privacy coin that has a strong working product and is currently developing a novel way to stake Private balances. This means that you will be able to stake your balance without anyone knowing.This tech will be a first for a POS coin and is set for release in early 2019. at a price of around 20ish-30 cents currently Spectrecoin could see amazing returns in 2019. I for one am weary we will escape the crypto bear cycle in 2018 but I could be wrong. Another, more well known coin that I also believe in is Cardano. Out of the top 20 coins I think cardano might see the biggest returns if you invest now and hold. In 2020 There is suppose to be the widespread release of atms that will accept Cardano and this will introduce stong real world applications to the currency. Cardano is still very speculative but I think it could be a big player in the future.
