I think it is very risky to invest in a cryptocurrency if it is not listed on any exchange. Because we do not know when the currency will be listed, where it will be, it is uncertain whether its value will increase or decrease after listing or whether there is enough doubt as to whether the currency will be listed at all. Many such projects will be very good, it was seen that there was a flop just before the enrollment. Therefore, it is better not to increase the tension by buying tokens without enrollment.
