I don't know what is going to happen in future but I prefer to keep all my portfolio in bitcoin now than spreading on the altcoin. I have see my investment in profitable zone since the beginning of this year because I decided to do that since last year end when almost all the coins you listed above went below 200ma and uphill now there could not recover. I will began to look into altcoin market again when I started to see recovering above 200 moving average.
Actually I dont think it is a wrong idea to diversify into some altcoins, because if you look at his statement, I think he said new coins which I am sure that his old portfolio must have consist majorly of bitcoin, and in bitcoin investment, it would get to a pint where you can no longer accumulate because you have accumulated enough at cheaper rate and then because it is becoming more expensive, you will have to diversify into altcoins too that has potentials and are quite still cheap to buy.
Most of the altcoins that the op listed here are really solid projects which I can see some IEO projects there too, it shows that the op know how to select every well, and I am sure that this altcoins will basically be the ones to make him a millionaire in future depending on the amount invested.
