Both of them, between Bitcoin and Altcoin are the same because they are both unpredictable, both in the short term and long term both are always at risk even though you can also get more profits. It's just that, you must be careful in choosing the best coins, after that hold and I'm sure you will benefit from your patience.
the coins you mentioned are just as good, it's just hard to guess when a coin will rise. if you have coins, in my opinion you have to keep holding the coins you have until prices rise high. often to check the market so you know more about rising and falling coin prices. if you wait patiently, in the future it will make a big profit.
