I have been trading in crypto for last one year and I have seen one trend that whenever a hardfork is announced that coin shows bulls run before the event. Hardfork is for the new upgrade. Every Bitcoin hardfork gave us new coins. But most altcoins do not give new coins in hardfork.
Hempcoin has hardfork planned on 31st January 2018. It is available in Bittrex.
Also, CampusCoin(CMPCO) is going to reduce its total supply. In their official GitHub dev account, they have posted.
Version 188.8.131.52: Block Reward switched from 1500/block to 500/block, set at block 100,000, block reward halving changed to every 1 million blocks, changes total supply from 2 billion to 1.2 billion. (Never implemented)
Also in 2018 add Binance(BNB) in your portfolio as Binance(BNB) will burn 100Million coins. So try to add in dips. Binance will have three successive coin burn in April, July and in October.
