Bittrex Global
XRP in my opinion is still having a lot of space to move up because of its history of reaching 1K Satoshis per XRP. So in my opinion just like BTC you will never go wrong in picking it to invest in because it is one of the leading crypto assets out there that has a lot of users and you can see it in the volume in exchanges in how it is being traded.
That is why if you have some extra money that you rather use to invest rather than buy things that you do not really need then XRP is one of the best choices out there because of the factors I have aforementioned. But of course always take my words with a grain of salt and do your own research before venturing out in such financial options where the volatility is high and you are at risk of losing money due to a myriad of factors such as FUD, bad news, manipulation, or just simply your crypto is dying out.
My advice is that if you bought a coin and it went down just like any other coin in the crypto market. Just hold it and wait until you can see that you can profit already by selling it in a higher price otherwise if you sell it for a loss than you lost. I believe that in the future almost all these cryptos will gain in value so it is all worth it to wait, and wait, and wait and hope that your crypto will pass the test of time and change your life for the better.
