I recommend to consider Monero.
However, as you said - it is important to hold it patiently. Buy some coins now and send them to your mymonero-wallet and come back 1-2 years from now. You might end up being a millionaire or even a billionaire (depend how many coins you are owning), in fiat terms of course even if bitcoin dumps big time.
from my personal experience, i would never put my trust in any altcoin ever more than a couple of months tops. all of them are good for getting in and out of quickly without any hesitation

for all i know 1-2 years from now ....coin can be worth 1 satoshi like a lot of them that are at those levels now and 1-2 years ago people were claiming the same thing you are today.
