I have a question.
What is better? To keep your coins on some Exchange site or to open wallets for each coin?
I would like to hear some advice. What are pros & cons of each option?
Thanks
The best practice is to keep only those funds on exchange that you want to day trade or hold on mid term. For other assets and long term investments is better to use cold wallets.
In this situation, it is recommended to hold nothing at all on the stock exchange. As now in the market of crypto-currencies there is a falling trend. In these conditions, it is very difficult to trade!
