I'm a freelance tech writer, social media marketer for ICO's. Many of my clients offer to pay me in cryptocurrencies.
What are your thoughts? Is payment in cryptocurrencies better or shall I stick to payments in fiat currencies?
It's entirely down to you, if you are comfortable in dealing with them and selling them for fiat then sure, if you are not then don't. You have to consider however if you will lose business by not accepting such payment. If you won't lose business I'd stick to fiat, it's just easier for you to manage that way.
