I can suggest GVT,
when GVT started its ICO, I was a part of it, It only cost around 1usd per token that time. And because of its little supply, Its already surge 35usd per token, as of the moment, it only has 25usd per token because the price of bitcoin is currently low, but I think it really has a good potential to surge more because of its limited supply.
Do they offer dividends for holding? I am currently looking for the type of coins.
Well, if you are looking for dividends which you didnt mention above, I would suggest you to buy bitcoin and NEO. Bitcoin does pay interests, but there are many bitcoin forks that occur which in short is a dividend and free money. There were many bitcoin fork in 2017 such as bitcoin gold, bitcoin diamond and also in this year such as bitcoin private, etc. NEO generates GAS if you hold it in neo wallet therefore generating passive income overtime. GAS can be traded for other crypto assets or sold for fiat money.
