I was wondering if I missed linking my Bitcoin for the first round is it too late to link it now?
It's not too late, you can link now for the second and upcoming rounds.
Secondly what's the easiest way to link if I'm using Jaxx?
Don't know much about Jaxx, I assume you can't sign a message, so sending a micropayment would be the easiest.
I'm guessing I'll need to transfer all coins to a single address as I don't see it working otherwise? Anyone else have similar problems? Thanks!
You can link as many addresses as you want. Depending on what's the less costly for you, either link all your addresses or transfer all your funds to one Bitcoin address that you linked/will link. By the way, the funds should be there the day of the snapshot (meaning you are not obliged to transfer now).
Anyone else have similar problems?
What problems

?
Thanks!
You are welcome.
