I`ve never heard about this BitGrail exchange platform.So this is just bankruptcy,it`s not a hack or some exit scam.Why so much competition among the big crypto exchange platforms a was expecting some platform to bankrupt.The sad news is that this bankruptcy might scare the italian people away and they will leave the cryptocurrency markets.
Bitgrail exchange was little bit known when that NANO- Raiblocks incident happen. Even myself didnt heard this but when issue arise about nano then it seems out they do already ruined their credibility as an exchange. Now italian autorities seize out bitcoin. For what? Even though they are bankrupt its not just right to get coin holdings into its users. These kind of risk can happen on any exchange which as a user or trader we should really be sensible to store out our coins in our own wallet not the exchange ones.So, if theres a problem you wont really got worried into your holdings since you do have the full control.
