In 2018 I think that not, but in 2019 or one year later, I think it's possible. XRP has very good thoughts which I like and I invested last week big amount too. So I hope with you.
Ripple will not make a millionaire out of anyone. With so much supply, you have to have a lot of money to do it. It is not able to grow so much. If it increases by 2x then you need about 500k $ or more for investments. I think that with this amount, you can invest better than in xrp.
