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

currently you won't easily find an altcoin that can be easily x2 or x3. Our market is at a bad time. But I'm watching an interesting altcoin, it's meme coin, Banano.
I bought it when it was at $ 0.0008 and now it has increased by more than 36%. 2019 will be its great development year and its value will easily increase by 100%.
