I have tried this on many occasions and it works absolutely fine for me. With patience, i can hold a coin for about a year or even more and normally, it does not happen in vain, in the end, sometimes i'm able to earn 500% or even more increment. I remember one coin Zcash Gold surge from $150 to $5000 within a period of 3 months. That's the power of patience in cryptocurrency, if only you hold the right coin.
