iam never use bot in trading
trading use bitcoin and altcoin is not good use bot
is selling bot is accurate i think never selling but self use bot to get maximal profit
Like you mentioned, trading bitcoin/altcoin pairs may not be a good idea but if the altcoin been traded against bitcoin is one of the popular ones that has value like litecoin, ethereum and co, then the use of bot in trading them may be applicable and profitable in few instances and not all the times.
