$mara been in since .64. IMO always keep a core position as it's going to hit $7-10 this year. Way too much good news lately around BTC and with the fed printing money to a crazy degree it's primed. Once the PayPal news is official will have a big bump. Heck the news around banks officially supporting BTC is big news.
I also been trading quite a bit on it. Bought and sold all the way up to 2.90. I think it retraces back towards 2 where I will reload.
