4 Flash Buy Signals for Altcoins Following the Binance Shock: Here Are the Flipside Targets October ended on a negative note for the cryptocurrency sector due to the $6.3 billion Binance hack, but Binance was able to recover the withdrawals and return much of the stolen funds. Analyst Ali Martinez identified four cryptocurrencies—. Cardano (ADA), Algorand (ALGO), AAVE (AAVE) and Radium (RAY) - which are showing buy signals, indicating a potential recovery in the market. Martinez is using the market pullback to build a diversified portfolio of five altcoins, including Injection (INJ), Sui (SUI), Midnight (Night), Pango, and PROMT, which he believes have strong buying opportunities.
