As of right now, the Pulsechain project has not yet launched and there is no date to be set. Hence, no Pulse cryptocurrency is available in circulation. However, there is an upcoming Pulsechain sacrifice period of 30 days where you can sacrifice many of your erc20 Ethereum network coins and tokens you hold in your wallet in exchange for a ton of Pulse. The ratio of your $ amount sacrificed in relation to how much Pulse coin you will receive in return has not yet been decided on. Most are saying there will be a bit of Pulsechain and Pulse (PLS) available on Uniswap and small exchanges.
