to find out a coin that is going 10x is really hard, lets be realist.
But 2x - 3x is far more easy, any thoughts?

x2 and x3 are not easy. Investment is risky and you can easily make your portfolio / 2 or / 3.
Don't be too greedy to invest in altcoins with just empty promises. be alert and put the profits from 20-30% is best.
