May I throw my hat into the ring by promoting exvo.io ? Very happy with that exchange and the people on their discord are very active and helpful, especially to people trying to add new coins.
They also got some respect from me for not exposing their customers to some random coin devs, so it shows that they care for their users.

Just my 0.02$ to this shit show. ;-)

thanks, syncing now

Also, any reason I cannot connect to the stratum/pool? (none of the 3 ports)

Lots of blocks are backlogged, may need more nodes. Also cannot connect to any node to sync blocks. :-/

Or get a Dockerfile / docker container:
https://gist.github.com/spiegeleixxl/3cdb4267109b3b1eada5c36c2f78e9c1

Alpine Instructions:

apk update && apk upgrade && apk --no-cache add gcc make wget unzip g++ libssl1.0 boost-dev miniupnpc-dev libqrencode-dev openssl-dev libexecinfo-dev boost-thread autoconf automake libtool libevent-dev curl-dev gmp-dev
wget --no-check-certificate -O master.zip "https://github.com/JayDDee/cpuminer-opt/archive/master.zip" && unzip master.zip;
cd cpuminer-opt-master; sh autogen.sh && LIBS="-lcurl" ./configure && make && make install

Then you can call cpuminer.

Anyone looking for a (crude) Dockerfile for a wavinode?

Dockerfile
https://gist.github.com/spiegeleixxl/71d0913f38989dbf98130a0b63f3126f
docker-compose.yml
https://gist.github.com/spiegeleixxl/b67bb88eba896d6fdb4d7a272c6e703a

Create "data" directory in the directory where Dockerfile is, and go wild.
(docker-compose build && docker-compose up)

Are there any protections against smartphone farms? Or ARM emulators, or emulate-compiling to GPU/CPU? Algorithm?

Maybe they encounter the same issue like the folks over at ELI Coin, where a couple of GPU miner basically swamped the coin with wrong positives and wrong algos. They mentioned something about a YIIMP patch, if that's what being used over at Supr...

Maybe all of these issues are related to this:
