Which crypto do you trust more, the one that is traded freely and nobody knows where the rate will go tomorrow (like Bitcoin) or the one that is under control of its developers (like Ripple, more or less)?
Where you would invest?
In my own personal opinion, I would prefer both. I think it's all about timing and taking all of your time while picking a certain crypto to invest with. There are instances where bitcoin's value rises very high and there also time that the same thing happens for those crypto whom developers have control with. It's more about the season and also, don't forget, your strategy. While the price of a certain crypto is not that high yet, keep on buying, afterwards start holding then sell it our when the price is already too high.
