It was one of the most promising projects that I considered as an investment, but alas, something went wrong and the project, or rather its price, was blown away.
What went wrong was that some people started sabotaging their own investment and talk shit about it. Everybody acts differently under pressure and it can mess you up pretty good if you enter ATH and see it drop over 90%. Same with people who got Bitcoin at $18k, they swear they never touch cryptocurrencies again because they lost their life savings. Only difference is that Bitcoin is so much bigger than Byteball, so if somebody did a bad investment choice with altcoin then it is heard lot louder.
But it is kind of human nature to FOMO when the price goes up and invest ATH and then panic-SELL when the price is down. For successful investing, you need to act against the human nature and buy when it is low (now) and sell ATH. People who can't change that behavior, I would suggest them to try to build their own index-fund with TOP10 cryptocurrencies (stay away from altcoins) and then do portfolio balancing, but that is not sexy because gains are lot lower that investing into lower altcoins (basically, lottery).
