Their community looks like the early Bitcoin cypherpunks community, lot's of innovation, lots of nerds, lots of technical talking.
If you are seeing positive with that then join them. But you have to know that many projects and fans already said the same thing with the projects that they've supported before but none of them actually replaced bitcoin.
Currently it has a $70m market cap........... Should I sell part of my BTC BTC for ERG?
$70M is still low but who knows if this project you're believing could be near with the top ones. And if you're wanting to sell your BTC for ergo, you decide. But for me, I have learned my biggest mistake in the past and that's not to use my Bitcoin for buying some alts that I like to own.
