Concerns
NEXO token is classified as a security token because of its dividend paying nature, so none of the current high-volume exchanges are able to list it. It is uncertain when exchanges supporting security tokens will operate and generate sufficient trading volume.
There are a number of operating blockchain projects focusing on using cryptocurrency to obtain loans, such as Salt Lending and ETHLend. Nexo will be competing with them in one way or another, although the entire space is huge and is big enough for multiple winners.
