I won't be putting my suggestion here right now since I am not focus in investing altcoins, but even if I am investing now,  56% is quite unrealistic, unless there's a big hype that will cause a sudden pump, and that kind of coin is something that we cannot predict.

I suggest you will evaluate your decision again, and I think Bitcoin is the best investment for now in case you want a safer coin.
Altcoin season will come, hopefully and maybe that's the only time we can expect that kind of growth.
