It is a Fraud/Scam. There is no arbitrage! Look at RBIS price, goes from 15 euro to 0.05 euro, 99% drop per year. If there was any arbitrage profit, arbiscam could have bought back the rbis-sjit token which they do not do (and which they promised in their roadmap). 100% SCAM, and mysteriously there were stlll noobs buying this scam while the license was withdrawn and there were many warnings.To their scam response:1: They have been succusfully scamming people for many years. Nobody ever made money on their Rbis sjit token. It devaluates 99% per year. And they broke their promise to buy the token back. They can not and will not buy it back, because their whole scam is build on the arbitrage lie. There is no arbitrage!2: You call it now authorizations. But Let me remind everyone that the LICENSE was withdrawn, and now they have a simple registration and they call it a authorisation. The scammer behind arbismart you can google and also it is published on telegram group arbismartscam. IT IS A SCAM! Just read the negative reviews. If you can withdraw your crypto/fiat, they ask ridiculous fees. The whole purpose is to lock you into RBIS sjittoken which then devaluates 99% per year, that is how they steal your money.
