Halving will be only in 2020. Therefore, I believe that during the 2019 you should not expect anything at all)
For me, i think this is wrong, we can ofcourse expect profit in 2019 because crypto currency is not all about bitcoin.
In this month, apollo token has brought about over 160% increase
in this month, gmb has fetched over 75$ worth of token
in this same month, crv has fetched 75$ (albeit an airdrop token)
if you are an airdrop or bounty participants, 2019 is the year of reaping profits of the tokens you own in 2018
