You have to reach the current threshold in order to receive your XRB.

Someone know why Bittrex only add BCH in the last 3 months?

They also added Cardano (ADA).
I heard they had legislation problems in the US that caused them to add very few new coins.

If I leave my xrb on Mercatox will I also get the forked coins?

A fork? If yes what chain will be the best and what names will have new coins and on what exchanges will be traded?

The price of coin is still low. Any news about online shop where we can use XRB to buy products, is already launched or when will be launched?

Join slack.raiblocks.net for faste support. May be you dont have enough space at disk C: ?

so raiblockscommunity.net will be the fork site (supported by mikerow, drizzt)
what name will this forked XRB be called now?
what's the fate of users using RaiWalletBot & YapRai? which XRB fork these wallets will support
too many questions, so little information I can find to understand the current situation 
last... should I move my balance to RaiWallet (own key) to secure my position on both forks?

There can hardly be a fork of XRB with continued distribution, if Collin (Dev) still holds control over private keys of genesis & distribution wallets (and he decided to stop distro and burn the rest). If this is still true, only Collin can either burn or continue distribution of original XRB - no one else can.

Ergo, if @raiblockscommunity group decides to continue faucet distro model, they will need to start the new chain with new genesis block.

Mate, it is not similar to BTC/BCC. BTC/BCC creates new coins in each new block (genesis tx/block). So if BTC forks, two new chains (BTC) + (BCC) have both ability to create new coins in each consecutive block.

XRB had all coins already created in genesis block, they were under control of the dev (Collin) and were distributed gradually to the faucet, through which XRB was distributed. So - if all remaining XRB coins are still under control of Collin, then no one other than Collin can continue XRB distribution via faucet. Ergo, unless Collin gave control of XRB to @raiblockcommunity group (which wants a fork), this group simply has no more XRB to distribute. They can only create new copy of original XRB incl. new genesis block and then, they can distribute this new coin.

What about news? We have new forks? What does this meaning? Newcoin for the same claim?
