I'd be careful with electroneum. They got $40 million worth during their ICO but they ended up launching a failed network where miners took advantage of early profits that were supposed to be for investors. Also take into consideration that there are now cryptonight ASICs but unlike Monero they have not announced any forks or updates to combat these. They probably don't have a good technical team and don't know how to do it.
Sorry that's incorrect - if you watch the Q&A with Richard the owner of Electroneum he states on 2 separate occasions they will follow Monero with a fork.
You can find it on youtube or on there social media pages.
I dont understand the failed network bit tbh? But I only started following them in Jan and yes coin price is down and they have had a recent outage which was bad form, but i dont see that as a failed network. Watch the video, there seems to be a load of good things in the pipe line, also everyone of the Q1 targets/roadmap have been met -
