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.
This applies directly to shitcoins. Here is a video on how to make money with shitcoins:

Monero has a growing community which is over 1 year old. The price has been pretty stable (the trading range has been pretty tight between 0.002-0.004).
Some of altcoins will become pretty valuable and I doubt bitcoin is the ultimate currency. The challenge is to pick the right alts to which stick to.
Premines are bad as the developers has no incentive to do their work but simply pump the coin and then dump and run away with your money.
Good coins there are just a handful, Monero being one of them and as it solves the key problems with bitcoin (fungibility issues and privacy) therefore I am a little bit heavier in Monero as I see it has potential to grow in the coming years. However, the odds for success is obviously pretty thin but each day the coins are mined and bought and stored away from exchanges, the odds for success increase a tiny bit.
Soon the coin supply will dry out and then there are time to pump the coin.
I hope as many people joins the party now as possible until it is too late. But don't go all in Monero though. Be smart.
