I'm guessing many of the buyers sucking up XRP are noobs excited about getting rich in crypto. If you look at Bittrex for example, watch the trades: Today I seen a panic sell of 20 tokens for $52 USDT, and there are many more like that. Purchases of XRP totaling $10USDT and less being made all day long. When you only have that much money to experiment with in cryptos, then I guess that is money you really can't afford to lose... which they all will.
