lol. but anyone can build an online retailer to compete with Amazon.... and how is WMT online doing?
I can't believe you brought up Amazon, because I almost posted, bitcoin isn't like Amazon. If you really think they are comparable, you don't know shit....
And that the altcoins are riding the waves of bitcoin? Who cares? Is that your argument? It just shows that the trailblazer makes it easy for the competitors to move in. One more advantage for the competitors, they don't have to break new grounds...
By the way, (looks like I have to spell it out) the point with alt coins is: If you are a vendor already accepting bitcoin as a payment method, there is really no good reason why not to accept the most popular altcoins. Just like if you take Visa, you might as well take Mastercard too...
And you might want to read up on proof of stake methods, to see how many more advanced alt coins are there...
If you don't believe in alt coins, why do you own so much of them?
