BitBlocks will make a big swap prioritizing the optimization of the wallet, the speed of the blocks and implementing the system of masternodes.

The swap will be 1/2 so if you have 100 BitBlocks before the swap you will get 200 BitBlocks after the swap.

The swap will be made directly by coinexchange.io on November 10 at 12:00 GMT -3
