Pretty much ALL ALTCOINs dumped at the same time. The same ALTCOINs bounced at the same time 40%, 50% some even more. Just wait until the dump more since Whales must lock in Profits.
You really don't need to scan the market because you will see the exact same thing on all coins. FOCUS on the top ones: BTC, ETH, LTC... you don't need more to make some money.
For future any queries
