I bought Rippel because the price is still very low and I see greater possibilities of growth.

The price of Monero and Dash are too high to make an investment and get similar results to Rippel.
Rippel growth in the last 24 hours is 64.55% compared to Monero 18.77% and Dash 7.97%.
If in all three cases you invested $ 1000, you would have earned $ 1645.50 in Rippel, $ 1187.70 in Monero and $ 1079.7 in Dash.
If you give me to choose which of the three currencies I can invest in, I choose Rippel.
Thank you for ask.
