Bitcoin is better than any other cryptocurrency for a simple reason that other cryptocurrency such as Litecoin and Dogecoin could hardly be used to purchase for retail commodities even if they are accepted by the dealers. And they are usually used for investment or storage value.
well, Bitcoin is the ORIGINAL idea for the whole cryptocurrency thing and others are just copies or immitations in other words, and sometimes with some innovations or changes but nothing significant YET.
Bitcoin isn't the orginal. It's just been the most successful, but I also agree with the post above the transfer rate on Bitcoin is atrocious. I think of Bitcoin in the same way I look at cellphones or television. If you think Bitcoin is at the forefront of crypto technology, then your head is in the sand. Bitcoin is widely accepted, because of the early investors and crypto enthuasists. Bitcoin will most like always be around as the core value base of crypto in the same way as gold was for a longtime the base of all fiat currency. Bitcoin is cryptocurrency Gold, but much like gold, it is difficult to obtain and time consuming to transfer.
