I think it's very difficult, since most of the altcoins depend directly on bitcoin, some indirectly, I think it can be easily seen, because if bitcoin goes up, the altcoins start doing it.
Many times the altcoins begin to rise and may have a good run, but if the bitcoin falls, so the altcoin has the best moment will fall, it is very simple, because they depend on the price of bitcoin.
If the currency did not fall when bitcoin falls in price, I think that at that time is different, everything changes because it would stop depending on the leadership of Bitcoin, and that scenario is very difficult to happen, I think it is impossible.
The only way is to get an altcoin that does not depend on bitcoin drops or that does not depend on bitcoin, if bitcoin goes down, that currency should not go down, that currency has a life of its own, and that can be achieved when some kind of liquidity based on gold, diamonds, precious stones, something that could support possible worldwide dumpees, and that would make you think that you have another way of looking at the speculative market, I think that is the only way and it is very difficult to happen , apart must meet many standards, that has a lot of history, that is to say that it has at least 10 years with that stability, and does not become a bubble, or as in the case of tulips in the stock market.
