don't forget guys, the only reason DOGE is still relevant and at its current price is because Elon and his followers keeps pumping it.
i have no problem with DOGE, but i don't like how the price can be easily manipulated by a single person.
So you think that DOGE only survives because of one man? I don't know when he first mentioned it, but I don't think he should be the reason why that coin is still relevant. As for the pump, most altcoins follow BTC, and I don't see that the current price of DOGE has anything to do with the person you mention - he has much more important tasks than pumping any coin.
DOGE is currently 80% dependent on what Elon says about it. Before that, (around 2019) it was really miserable, being bought for 14 satoshi's. One of the important advantages it had as one of the oldest was that it was listed on all exchanges and with very cheap transactions.
I agree with LoyceV, DOGE is not the best choice for an exchange that operates exclusively with its own funds so in case of a big price drop, you have to wait for Elon Musk's new tweet to reduce the loss.
Adding Doge adds the risk of someone exchanging a load of Doge for Bitcoin right before a price drop, making eXch a Doge bag holder. I wouldn't want to run that risk.
