Many beginners want's to become a trader, but they are skipping the process and start looking for an exchange as much as possible without knowing how to trade well. Trading is not that easy, it requires a lot of research, and analysis treat trading as your Job!
One of my friend asked me about the current exchange he is using, and what coins to buy so he can make profit. Well, I don't give any advice regarding on this one because for me if you want to make profit you should know it on your own. I just give some advice that if he really wants to become a trader, go take the process, learn more and you will see what coins to buy especially during this bear trend.
How do you see your trading activities? Are you just here to buy and sell or you are here to have more good coins and hold it until you make profit?
You have said it right you must treat your trading as your job. If someone ask me about the current exchange and what coins to buy for me I will tell them that it will depend on the exchange that you want to used and look for a coin that has a good review on the exchanges that you will used so that they will know on their own what coin they will used and they will not blame others on suggesting that coin. It is not hard to know what coin you should use to trade you just need to do your job, no one is responsible for your job.
