Raiblocks is a cryptocurrency designed to be a low fee crypto and fast transacting.
They had a coin distribution through captcha solving (such an unique way to distribute coins).While the distribution the price didn't go higher than 0.12$ per coin.
But,when the distribution phase came to an end,the price incredibly rised to 15$!
Let's see the charts:
As you can see,early May,the price was 0.009$
Now it's 15$,that's insane! That's roughly 2700% rise! (That means if you invested 10 bucks when it was 0.009$,you would have now 27k$!)
I wish I had put my money on it back then.
