Trading bots are programs that automatically buy and sell Crypto Currencies on exchanges based on a specific strategy.

There are many different trading bots, some are cloud based, others can be installed on a local computer or your own server.

An easy to use and configure bot is Crypto Hopper. They allow you to connect most of the major exchanges, they have a very active community and they offer a free trial month to check out all of the features.
