the problem is in regulation of these institutions. In some cases, they just decide to robe the users and nobody can't stop this.
Regulations must be done in all countries in that case otherwise anyone could open these exchanges since It's done online.
I think we should educate people more instead of asking for laws and regulations. If each one us has the basic understanding of how crypto works, on how we could keep our funds safe by having full over our private keys and not use online platforms for that purpose, and also that we shouldn't trust an exchange that its team is not known the public, the design and the effort put in the website should also be taken in consideration, the support response time or basically anything that shows how unprofessional and careless the team is.
I also don't understand why people use unknown exchange If there are others are big, trustworthy and have huge trading volume and If there is an excuse like "the coin is only being traded there" then It should be a red flag not only for the exchange but also for the coin because nothing good comes from a coin being traded in unprofessional/unknown exchange (e.g YoBit and the coins there).
