of course I prefer Bitcoin, because in my opinion Bitcoin is better than Dogecoin and this is my reason why I chose Bitcoin :
1. Bitcoin dominance is greater than Dogecoin
2. Bitcoin is more popular than Dogecoin
3. Bitcoin volume is higher than Dogecoin
4. most altcoin use pairing with Bitcoin, but Dogecoin doesn't have it
5. Bitcoin is the king of all cryptocurrency
Lets put up some numbers.
1. BTC - 46.81% DOGE-1.32%
2. Popularity? Price speaks for itself
3. Overall cap - BTC $1,145,551,280,739 DOGE- $32,377,409,171
4. Merchant and institution adoption is higher on Bitcoin
5. No one beats up the Father of all crypto
With those numbers alone then you could actually tell the huge gap.
