RAIBLOCKS might be the biggest thing to happen to crypto space since Bitcoin. 

It's not like most of these coins which are forks of Bitcoin code.  Some of these forks are straight out scams like Verge which don't even do what it says it'll do.

Raiblocks is a completely new system, in a way similar to what Iota did, which allows for scalable system (allowing 7,000 transactions per second) and with the speed of 1-2 second confirmation times.  That is revolutionary in blockchains that are decentralized.  Ripple is a centralized validator system and even it doesn't achieve it. 

Also, with most of these coins there is a huge pre-mine with founders, dev teams, companies or early ICO keeping a huge percentage of the coin.  With RaiBlocks, the founder distributed Rai by allowing people to solve captchas early  in the year.  Rai was worth very little at the time so mostly people in developing poorer countries accumlated a lot of Rai (Venezuelans for instance).  So there are no big whales who can dump or manipulate this price yet. 

I copied and pasted this from someone else's post, it gives an account of RaiBlocks blockchain and how it works:

RaiBlocks uses a block-lattice structure. Each account has its own blockchain (account-chain), equivalent to the account's transaction/balance history. Each account-chain can only be updated by the account's owner; this allows each account-chain to be updated immediately and asynchronously to the rest of the block-lattice, resulting in quick transactions. Since blocks can only be added by each account-chain's owner, transferring funds from one account to another requires two transactions: a send transaction deducting the amount from the sender's balance and a receive transaction adding the amount to the receiving account's balance.
