For anyone stuck with the MEGA limit, you can use the free chrome extensions Zen Mate, and change your location to a different country and there goes the limit. Two location changes worked like a charm for me!
Alternatively use 2-3 different Mega accounts.
I used my account and my wife’s.
Resetting your router after every 3 file is another option. It resets the IP Address.
I have a static IP address, and setting up a temp account using something like temp-mail didn’t work for me, so VPN was the only way. But sure, if someone has a dynamic IP than that’s also a viable option!
