I wonder what BTC will be at if doge could make it to 20k per coin I'd say this is impossible mate, remember max supply is what's pulling coins like doge back, BTC can't make it to 50k if max supply is over 1 billion it's simple math 
Lol Obviously OP is just trolling and you can see that in His follow up posts in this thread , and Doge will reach 20k? then Bitcoin will be a BILLION DOLLAR A PIECE? this will never happen even if cost a lifetime , Dogecoin may stay stronger but the highest this can achieve is at least 1 Hundred Bucks because the supply is huge and cannot imagine how can this take that level.though there are still possibilities if Doge management decide to Burn their coins time after time until the lowest supply reach then this can be change .
