Will Bitcoin become the new gold and will Dash be used for daily payments? Any other potential crypto currencies in mind that can replace BTC or DASH?
No. Bitcoin IS the new gold. And, after a couple more fixes, it will be still Bitcoin used for daily payments.
Dash doesn't fit to this equation. There are many faster coins, there are other anon coins (and there will always be a debate on how anon really is one or another), there are more stable coins.
The only thing you try to do here is to advertise Dash. You don't really want to see other coin names here, so don't ask for them.
