We are now in the future yes,but we cannot predict what will happen 3 or 5 years from now maybe a new coin with revolutionary features that could over shadow what bitcoin is offering to it's users now..
I doubt that there will a new coin which can move or even collapse bitcoin with all it's commodity of users only during 3 years . Bitcoin is strong crypto currency which have so many users in the whole world.
By the way just keep believe in bitcoin and join to "playing"with bitcoin, you will found a feel that can give you a proof.
I think the possibility of coin that will replace bitcoin will always be there, because we know the technology will always be updated. Likewise with digital currencies like bitcoin, maybe not now but someday I think the day will come bitcoin to be the number 2. But for now, as you said I would enjoy, believe bitcoin and continue to use it for the benefit. Thank you
