Raiblocks dipped from it's high of around $17.25 to its current price of around $13.50 today. This coin hasn't even been listed on a major exchange yet, and somehow its almost in the top 20, once this coin hits an exchange like binance or bittrex, I expect a huge increase.
Not only that, but Raiblocks has been gaining a lot of momentum, and I don't see it slowing down.
This might be a good time to buy, kake sure to check it out and do your own research before purchasing, but this coin has a bright future.
