I am not sure about this. According to the media reports, the dump by the scammers started a few weeks back. But when I check the charts, I can see that Bitcoin is up by around 6%. Some of the other cryptocurrencies have also gained value. From what we know, the Plus Token scam involved the following amounts:

180,000 BTC
6,400,000 ETH
111,000 USDT
53 OMG

This is a partial/incomplete list, but you can see that BTC is among the stolen funds. So I am really surprised with the Bitcoin rally today.
