in 2018 crypto currency will take a few serious knocks. It's already beginning in South Korea and as governments realise (remember - governments are run by techno luddites who know nothing) that this vast wealth is not getting taxed, they will start curbing its freedoms. Fact is (and this was from a crytpo guy talking in a financial article) crypto wealth is invisible to govt and also avoids tax. So, the security of your country, it's servants, education, health etc, this all needs funded. Crypto isn't doing that. As Papahyooie says, be patient but for other reasons.
I'm not even close to standing on the same street as an expert on crypto but I've said before, the process isn't going away. What will disappear is the gold rush, leaving us all with cheap(ish) 2nd hand cards. Give 2018 a chance to knock the reality into this craze.
Just happy I got my card when I did.
