fuck no it doesn't , here is why :
FUCK KEY CHAIN !!!! MY CONSPIRACY THEORY : IT'S A SCAM OF SOMEONE TO MAKE US INSTALL SOME SHIT ! FUCK THAT CRAP. IT WILL HURT STEEM/HIVE. I WANTED TO PLAY THE SOCCER GAME, AND COULDN'T BECAUSE OF THIS SHIT INSTALL
DON'T BE BUFFOON ! WE WANT BTC/HIVE RAMP
AND FUCK YOU EVEN MORE IF YOU DISAGREE
How is it a scam? It is not like they charge people to use it. Not every program is going to work on every system. No one forces you to use Keychain, no one forces you to use Hivesigner, or to use any of the password managers out there. You can always copy and paste what ever password is required.
You want a BTC/HIVE Ramp, me I don't care.
Have a capital day.
