Sorry bro, but you are basically coming to the wrong conclusion. You did everything right with XRB except that you sold them. So what should we learn from this? Do your research like you did with XRB (or however you came to buy them), and buy again into coins that are still cheap now. Since you mention Raiblocks. Colx will have similiar features and is still very young, but do your own research. And then... This time... DONT SELL THEM for a quick buck Good luck!
Yeah, I think I learned something with this mistake. I'm still new to this cryptocoin market and I'm still learning. I did some research and decided to invest in this crypto because I believe it is a great coin. However, I really needed the money and decided to sell it (although I could have got the money I needed in some other way besides selling my XRB - and this was my mistake).
Thanks for the advice about Colx. I'll take a look and read about its features!
