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?
I don't fully trust the business owners. Many projects in development have failed. My focus is now only on Bitcoin because this coin dominates the market. Even this makes many altcoins decline. Bitcoin in 2019 gave me an advantage because, at the beginning of the year 2019, I have withheld Bitcoin.
