Overall yes. But it doesn't seem like this year. Trading, bounty, Ico and even mining are less profitable this year, very different from 2017. But to be honest, cryptocurrency has given me hope and a great opportunity to get what I want and get what I feel is impossible before. Until now I am still interested and will continue to survive, I'm sure this situation will improve.
It is right that this year the profit from these things are lesser but the excitement this year is that there is less competition this year the bounty campaigns are paying high and the difficulty in mining is lower so we can collect more coins in this year.
