Do you ever hear a song that is even better than the original? Be careful who you voice that opinion to - one may say there's no way anyone can sing a Bob Dylan song better than Bob Dylan.
I call bullshit. Just because you did it first doesn't mean you did it best. Luckily for BitCoin, it has many many years to improve to where it is the longstanding best. Time will tell.
As far as there only being one crypto in the future...I also call BS. The real innovation here is the evolution of data. I think it will encompass much more than the replacement of fiat. Blockchain technology is no gimmick, we are in the prenatal stages of true change that I personally believe will change the future - for the better.
That being said, we are in a market that is extremely volatile and potentially extremely profitable... even though any such market is zero-sum at the end of the day (what one gains another loses), I and many others think we can be on the winning side of that equation until the time comes to determine what's actually going to stick around to be a part of the revolution.
Just my thoughts.
