In a Telegram group I read that it was around 125.000.000 XRP that was also stolen from them
Was there a source given with that info?
CoinDesk cites Bloomberg as source and provides the following numbers:
$533M stolen in total, and 500M XEM (already worth over $500M if we use todays starting price).
125M XRP added to that would mean the total is a lot higher, which seems unlikely, given todays press conference by coincheck.
