well, this is a great topic, but I am afraid half the posters here will hijack this thread by spamming the altcoin they hold
Bring it on!

Already started:
NXT will destroy all

Maybe it can be replaced with ETH or bitcoin cash. I know bitcoin is the number one currency and mother of all alt coins but we should not forget second and third coins which are Eth and bitcoin cash. Both currencies have the huge stamina and they're increasing more than bitcoin since BTC is losing its price I don't have any idea why it dumping but if you look at eth and bitcoin cash they're going up if the things happen of 1 year I can bitcoin not only replace but it can vanish.
Bitcoin cash is more inclined to go in that direction because until now the price is always okay and able to survive as well as bitcoin.
