The cryptocurrency market is unpredictable and we must always remember this. Based on personal experience I can say that investment in TOP-20 is most reliable but sometimes less profitable than new projects. I would pay attention to exchange coin like BNB, as they develop very fast and implement new features all the time. Development of new technologies like SPoS from Vsys, with new model of masternodes and coins leasing attracts more and more attention. RLC is the other project that will suprise us all soon. I believe that only strong projects with great teams behind them who follow the roadmap milestones, have great communication with the community have good future.
