BCH, BTG, ETH are recomended if you want to invest this year. or BTC while the price is down.
Looks like you are not aware what is going on with BTG as he are under 51% attack and i consider it as a failed fork already, i am not sure whether converting DASH now is a good move but it is a good time to invest in the top coins, bitcoin is always the best option along with bitcoin cash and NEO is also a good one, you can also check for other token projects which has some potential.
