The exchange and the project party jointly issued currency for the first time. The exchange participates in the selection and incubation of project tokens and makes endorsement with its own credit. If the exchange is down-to-earth, it will not go too far. Under this premise, IEO's project selection and operation are many times better than the previous ICO
in the first quarter, several Asian exchanges announced IEO, and I am optimistic about JYS in Malaysia. The main reasons are as follows:
-
with the background of traditional, high-tech and new financial instries, the team strength is OK, and the team has mature experience and quick reaction ability in project selection and operation
-
the object of IEO is the entity high-tech enterprises that need financing for development. The project party takes entity and patent right as endorsement, and the financing income is used for patent landing. The realization of procts and the growth of currency value are supported by real profits, which are completely different from the concept of air currency
it is said that the first IEO project will be launched in May. As it announced, the entity is a high-tech patent enterprise. When it comes to blockchain space, it's a real project that makes people feel at ease
