both kinds. While annihilation is a cure for all advance types, the added countermeasures deployed, the added able a aegis Bitcoin users will have.
Both continued and concise countermeasures were suggested. Recommended strategies accommodate accretion the assortment of bulge connections, selecting Bitcoin aeon that are baffled added away, ecology round-trip advice times, and alike encrypting all bulge traffic.
