Bitcoin is the leading dog till further notice.ALL crypto currencies trade INTO bitcoin, this is not a debateAlso, NO alt coin comes Near to bitcoins brand name recognition and industry penetration...practically nothing.This can change naturally, but as of now...this isnt closeI do think there will be a number of coins that will stay side by side with bitcoin, they will need to provide anything.For occasion, bitcoin as a retailer of value vs bitcoin for each and every day use.I believe an alt coin can not contend with bitcoin as a store of worth BUT one particular will have to increase up as an each and every day coin, and that would suggest it would have to perform properly with bitcoin.
