Cryptocurrency exchange with little information about their service and existence are not worth investing on because majority of them are scam,there are no information with regards to their regulation and their exchange developers team which makes it very risky to trade on.
Optimus is one of such exchange that has few information as regards to its existence and origin and has made away with traders funds by locking them out of their account and hindering them from making any withdrawal before they finally absconded with traders funds without any trace. So I advise you you proper research before putting in funds on any new exchange or better still stick to the already existing and trusted virtual trade exchange
