In my opinion, much stronger, of course, bitcoin. Approximately six months ago, Waves, perhaps, gave hope for a strong and hopeful future, but for today, I think that this confidence long ago flew away. The coin just fell to the bottom and it will be very hard for her to rise.
Bitcoin, in turn, also subsided a little, but this is normal for him, for winter there will be, as usual, great growth. That's when, maybe, Waves will show itself ... =)
