What is the fastest way of litecoin mining?
To my knowledge, all public manufacturers of scrypt asics has ceased their operations. This doesn't mean that there's no scrypt asics being produced, just that they aren't for sale on the open market. If you really want to mine, your best bet is to buy some used equipment on Ebay. However I doubt you'll be profitable, since you have to compete against huge Chinese farms with close to zero electricity costs.
