Correct. Bitcoin may produce less profit but it is actually very good at reducing the real risk of risky trading. I'm sure with your patience you might be someone who can be successful in trading as long as you don't rush into it because many people fail because they rush to become rich.
I think that all coins has their own bad or down times but BTC an be able survive longer than them, so even if we say we can earn less in BTC, at least it is going to be consistent. And if we calculate that all, our profit will still be greater than those coins whom we think can give us a better return.
Another good thing is like you said, it can reduce our risks. The OP might have a long patience but that wasn't enough in order to be successful in trading, although he admit that he wasn't a real trader, which is true, based on how he act. He only looks like a semi-trader and then an investor at the same time. I think those who rush are not always wanting to get rich, but they only like to earn some profits. Once they get it, I guess we can still say that they are successful.
