Do you agree with their decision? I personally believe that a big part of their business was from people wanting to do a lot of micropayments, because coinbase, coinjar and other online wallet giants have added fees and they were the only ones left yet to add a fee. But obviously that probably hurt them a lot and set them back on a lot of extra income as transaction fees skyrockets.
Your thoughts?
It's just a business decission. Miner's fees have always existed, but xapo was so kind to pay the fee for their users. They probably did the math, and found out the could maximise their profit by no longer paying the fees for their users. Sure, they'll lose business, but i'm pretty sure they would have done sufficient calculations to know their net income will rise with this decission.
Like you said, since the mempool is so full lately, fees have skyrocketed, so i suppose it's costing them to much money in the end.
