If I'm more interested in holding (indefinite time) than day trading, which altcoin should I invest in? Are there any one more indicated for holding, in your opinion?
There is no easy way to find a solid altcoin that will perpetuate in the future. Don't listen to others' shills, just do your research on as many promising projects you can and see which one has a viable product, a team that has put consistent effort in their development phases and continues to progress and most importantly inovate. I won't shill you a coin, I just want to recommend a coin on which you can do your research which is Stratis (STRAT).
