I have already bought LTC-it is a very good investment today! The choice of stock exchanges is huge, but if you are a beginner, I would recommend not only buying LTC, but also getting the benefits of registering on the exchange! To date, there are 2 good working exchanges, which to attract customers conduct the distribution of their tokens.
Register on these exchanges: https://bitsdaq.com/ and https://www.bcnex.net/?lang=en and you will receive additional benefits.
