I know, I know but if the development take a long of time, many cryptocurrencies can overtake these 2 coins because they are better to use, right?
Most of those "many cryptocurrencies", when they'll reach the number of transactions Bitcoin has, they may have similar problems.
Some of those "many cryptocurrencies", if their value rises over certain value may face 51% attacks because their network is not powerful enough.
Really, Bitcoin has this status for a good reason and will still keep it for quite a while. I see no worthy competitor yet.
