I initially didn't get the hype but think of this as more of an investment for the future.
Everything is going digital and what may be the norm in 20/30/40 years time is rather then having physical collectibles such as stickers/cards which can always get damaged/lost/stolen you can now have something to collect which is more secure, won't get lost and can't get stolen.
This may be what children and people of the future will become accustomed to, buying and collecting online.
Also... who's to say that Youtube won't limit/stop access to watching NBA recording
. What we have access to now may cease to exist in the future.
I see the potential.
