Nice! I was able to get ETH from L1 to L2 for $3 about a month ago. Used some of my HIVE earnings to buy cards and was really fortunate on the fees!
Also, if you are able, you can use a credit card to buy ETH directly on IMX using moonpay. It's usually a pretty good deal compared to making multiple transactions with fees.
I remember you mentioned about your transfer. It would be better I did it a month ago as well. But I didn't want to deposit 100 USD, I wanted less, like 40 USD or so, but I was afraid of fees. And now I want to add 50 bucks more :)
Moonpay was a great improvement for Gods Unchained and it is a good option for those who have no crypto and just want to pay with fiat and never spend tons of time for researching about crypto.
There are some negative reviews about commission and crypto rates though.

But personally I don't know - I have never used Moonpay.
Hmm. I know I've used it once, and while the fees aren't great, at the time they easily beat the gas fees. You can go through the motions of buying with moonpay, and it will show you the fees before you agree. For all I know they vary, too.
