First of all 10-20 coins is too much. I would advice to take around 5 coins. Concider the amount that you will be able to track an check the news. The amount of money needed to be rich is pretty relative. For someone it is enough 50k$ but for another people even 50mln$ is not enough. The starting amount can be easily calculated. If you are skilled / naive enough to think that you will make x50 of your portfolio then your 1k will become 50k which is still not that much. It is not that easy to get rich.
If it was easy then everyone would be rich by now
.
If 10-20 coins is too much or not again depends on what you are trying to do. If you want to diversify your risk and hopefully keep a steady gain (while investing some in you "up and comers") then I think that is a fine approach.
What I am talking about here is to
know your end goal. If you start out with 1-2k$ and your aim is to
"be rich" (say for you that is 100k$). Then the 10-20 coin approach will probably not get you there anytime soon. In that case I agree that you should focus on maximum 5 coins and hope" to make it big on one or two of them.
But if you start out with 50k$ and you aim to make 1M$ then I think diversification among 10-20 coins is absolutely fine. But again, you won't then put in 30-40$ in a coin and spread it out among 100-200 coins since then you will probably never reach the 1M mark.
So I am looking for, what is a reasonable
"minimum investment" in an ALT in order to reap the
"big rewards"? My conclusion was around $500. What is yours?
