actually $50 is a very little amount for investing.so you can try earn from this forum by social and signature campaign.and when it will a big amount then invest in only high ranked coin. Xrp,eth, and also i suggest you to buy waves coin.bedt off luck
Well, to be honest I would not suggest anyone to get with his money into Ripple, even if the amount is so small as 50$.You should notice that XRP is not even a real cryptocurrency, it was created by banksters and banks to make settlements between them.
It is not decentralized, and you need to know that the most important thing about cryptocurrencies is that they are decentralized so nobody can control it: it is not like that with ripple.
In my opinion, you should just get some bitcoins from signature campainings, so first make your rank higher and then collect more than that: and start doing some investments , e.g just buy ETH
