It is almost impossible, that same happens on any existing coins like Bitcoin, Ripple. The market is more regulated and it is more like a long term investment. For me, if any coins rise and drop in a large range, it possible is an Eygpt Selling mode and not really a good project we can invest for the long term.
The projects I am focused on now are Bitcoin Etheruem Stellar Ebakus Litecoin BitTorrent MithRil Bluze, some main coins some new ones.
For me hold more coins which you think good is better than just one, Bitcoin sure is the best and normally you can do 50% of your total investment. I prefer a stable increase rather than like expecting 50X 100X.
If the op is talking about such increase in a short time, it is absolutely not going to happen, I don’t think the next bull run will even be able to raise most of the very good coins in the market more than 10x, that is if we will even have any bull run for the altcoins again, but if it is for a long term prediction, I think it is possible for some coin, and when I still talk of long term, I am talking of real long term development like maybe in 10 year’s time, just like from the time bitcoin was created.
I think if we base it on the current value, that is almost about 10000x, so if any investor of those coins is patient enough to wait for their future, then they might be lucky to see such increase if the company does not wind up before then, because it will really take a very strong project to stay that long.
