OK, but these coins are in top 10 only by their market cap. You might agree that certain altcoins, which are the so-called outsiders often give the bigger profit, do not they? Look at the list of gainers (it changes often): https://coinmarketcap.com/gainers-losers/
For sure, this wasn't about which coins would give the most return on investment, rather which ones are leading the market. No doubt there will be some that appear from 'nowhere', and even more that give great returns further down the chain. Often the ones that post the biggest gains are way down, problem is a lot of the gains are almost immediately lost in apparent 'pump and dump' schemes. I think the top 10 are coins to hold as a solid investment for a steady return, as opposed to instant millionaire makers, the kind of coins you would move your profits from the smaller market value coins into for a 'safer bet'. But that's just my take on it, everyone has different investment strategies.
I agree with you, the top 10 coin is a coin is more stable than the other coins, I think we can see the change of board in the near future.
