I am not going to watch any more Bitcoin.com weekly updates until they go back to the old format. The Japanese girls seem like nice people but they don't know much about BCH.
So, when BCH was getting down to $75, I decided to send some $ over to coinbase to get ready to buy. Takes 7 DAYS! Price started going up just before the money "arrived", so I missed the bottom.😠
Same thing happened to me. I ended up buying around $100 instead of $77. Still good though.
I am not sure. But my gut is telling me SV is the way to go. But whatever happens as long as BCH remains cheap, fast, and reliable, that's the most important thing.
Dash's diff is adjusted per block yes. For your question to be a yes you have to make certain assumptions. I'm sure a quick google will clear everything up for ya.
