In other words, if you are going to be safe, you will choose BTC, and if you want to gamble, then you will choose altcoins.
Even though investing in bitcoin is way less risky than investing in altcoins, I don't think that people should look at investing in bitcoin as being safe. There is always a chance of something bad happening to bitcoin that can affect the price greatly (some kind of exploit, governments going hard against it etc) and people should be aware of it.
Having said that, I do have vast majority of my savings in bitcoin and I keep getting more. 
That possibility always exists, that's why it's not really wise to keep all your eggs in the same basket, but if something bad happens with BTC, the entire crypto market will sink like the Titanic. However, I think that BTC is quite safe for now because
they managed to profile it as something you invest in to make a profit, and less and less as a cryptocurrency, which is actually the biggest problem for those in power.
In fact at that time it was not predicted that the price of Bitcoin would be so expensive. $1k was a huge amount at that time so it was also very expensive in the context of that time. So there is no point in blaming ourselves for this. Financial conditions prevent us from buying and holding large amounts of Bitcoin at that time those who are financially strong are still able to buy whole bitcoins. Being middle class we always miss out on various opportunities. That's why the rich always stay rich and the poor stay poor. It is a cycle of the whole world
I would not agree if some people did not already then speculate that the price of BTC would one day be quite high, only they were a silent minority that few wanted to hear. I agree that $1000 was a lot of money for some back then, but it's the same today - but don't forget that in 2015 the price of BTC was around $200 for a long time, and in mid-2016 it was only $400 - that's really ridiculous compared to today.
I will say again that maybe this is an amount that some could not afford, but BTC has been cheap for too long for them to say that the
"poor" could not afford it.

In the end of the two choices between Bitcoin and Altcoins is looking for profits and minimizing losses from the effects of Bitcoin and Altcoins' trading effects, isn't it like Lucius?
I'm a bit old-fashioned when it comes to all this, because I was attracted to Bitcoin for other reasons, not exclusively profit, but later I saw that it can be an excellent hedge against inflation and value preservation. Let's just say that 99% of all my early altcoin investments failed long ago, so I focused on BTC.
Sathosi is already rich, because he still has a lot of bitcoin in his wallet. So I think nothing is free, although we must realize that without sathosi with his bitcoin we would never have known crypto currency. Because bitcoin is the pioneer of crypto. But I disagree if sathosi is not rich, I think he is very rich right now.
Being rich and not using that wealth is not the same. All those coins that he
"owns" are just the result that someone had to start the whole thing, but it is far from the fact that Satoshi wanted to be rich, or that there is even the slightest indication that he will ever consume that wealth.
Even if he wants it one day, the problem is that any transaction from addresses that are considered his would cause a real panic and crash the price of BTC.
