Except maybe for those who are actually holding some few tokens or coins from ICOs, I will say you should choose your exchanges first. Despite the fact that you are holding certain cryptocurrencies, making sure you are actually trading them on an exchange that is reputable is one thing I tend to consider a lot.

For instance, most of this shit exchanges, tend to make easy listing which in this case, you actually do not want to be on an exchange where you can easily end up losing your whole funds eventually, would you? At most times, you should even preferably wait for the coin to hit a better exchange first. That being said, I will say till date, I am still a big a fan of Binance until I see another good alternative, for so many reasons which I am sure a lot of people know already.
