i don't think you can call such a coin "deflationary" just because its supply is capped. it is like saying grains of sand are deflationary! it is already inflated and they haven't even released all the supply yet!
I think you missed the part where a small amount of XRP is destroyed every transaction. That is why there's 99,991,708,587 XRP available at the time I'm writing this post and not 100B.
Keep researching, took me 3 weeks of reading to decide whether to buy.
you can not decide whether or not to buy some altcoin by reading about it and its technology! we are in a manipulated pump and dump market and "research" like that won't help you one bit.
That is your opinion and I would even agree with it when applied to any coin that doesn't try to solve a real life problem.
But since Ripple is doing exactly that, I can't agree with you.
