If your ico token didn't perform well and then sell your ico tokens and move to the legit token. This is the best way for you to avoid your lose and take back your money to invest in another coin that has promising future. You can analyze the fundamental of your coin again whether it's worth to hodl or not. As far as i know if that didn't perform well and your token may dead anytime and it has no good development progress.
My advice for you to do your own research. if that's bad development progress and then sell your token but otherwise if that has a good development and you can hodl it for a bit longer.
The development needs the time but the performance of tokens must also be considered as an important thing for sure. That depends on result from your DYOR
