I can recommend you bounty from Huobi Russia. It's very good, and will bring a lot of profit. As you can see by a market the none of the exchange tokens fell lower ICO price. So you can be sure that will get a good profit.)
Yes, now, probably the most reliable are stock exchange tokens. And now there is a possibility to earn tokens from Huobi Russia. They do not even fall below the ICO price. The remaining projects did not perform well in 2018. Maybe in 2019 something will change for the better.
Perhaps you are right. I also hope that the bounty tokens that I still keep growing in this year. Great hope hold on stock tokens. Such as BNB, HT. Today I set a goal to attract more customers through the referral system, for which HTR is generously accruing. I'm talking about the bounty campaign of Huobi Russia.
