I believe that Ripple will not be the number one coin. Because the best has always been and will be Bitcoin. And no one can compare with him. All coins depend on Bitcoin and only it sets the growth rate.
Yes, BTC will always be the most valuable coin, and they are the king of the electronic money market, so no coin can overwhelm them, so I think if we invest in the main BTC is the safest solution for us and will probably earn huge profits from the market.
