In my own case, i have been using the exchange services in doing this, because there i have some of my coins which i may want to exchange to fiat or to another digital asset, so i don't bother in going too much in search of other platforms that could render the same thing they can do, even though to consider on their service fee, its something not encouraging to that extent depending on the networks, but still far better than the fist exchange system.
If you find a reliable and trustworthy exchange, it is no surprise that you will use it throughout your trading journey. Because trying other exchanges may pose risk as you have to learn their reputation first. But it is not wrong to try other trading platforms. Sometimes, they will give better offerings to their customers.
Try to read some user reviews or feedbacks before depositing money. You can already see a lot of reviews over the net. So don't be lazy hitting those keys. Because mentioning the exchange, a lot of hits will already come up. And if you are looking for a local exchange, you can get a good glimpse of their services among the locals. Word of mouth is actually a powerful tool when you are looking for some good services in town, right?
