I have been thinking about this and thought to put it here what's on my mind.
Just think that if some other altcoin has the potential to take place of bitcoins, like people are talking about Monero to take its place because of its privacy and security, what would happen to bitcoins? Is there any altcoin currently which can do this? And if yes, what would be the effect on bitcoins?
While there is a chance that an altcoin
could take bitcoin's place, that
chance is very small in the near future.
Yes, bitcoin has some possible problems: block times are big (would you use Mastercard if you'd have to wait 20 minutes to confirm your payment?), past flood tests shown that the network cannot handle well a huge spike in the number of the transactions (one reason being the pools that sometimes don't include as many transactions as they should, another reason the block size).
Bitcoin is, unlike people thought at first, not fully anonymous.
I know for sure (99%) that Dogecoin has much better block times.
I know for sure (99%) that Monero and other coins are anonymous.
These are things that give them an edge.
But neither of them have the strong network Bitcoin has. Dogecoin even experienced the fear of 51% attack; luckily it didn't happen.
There's no altcoin with the strength Bitcoin has. And while this holds true, there's no alternative to bitcoin.
