The difference between Bitcoin and Litecoin
Litecoin: Each block is processed by LTC in 2.5 minutes faster than Bitcoin using the Proof-of work algorithm, along with asynchronous memory instead of hard disk memory. Litecoin uses cryptanalysis algorithm.
Bitcoin: The processing speed of each block of BTC is 10 minutes and requires a hard disk containing .dat files over 20GB. The Bitcoin encryption algorithm used is SHA256. In essence, this suggests that Litecoin deals with more advanced CPU-based designs to exploit than Bitcoin.
