Does anyone keep count of wrapped Bitcoin either on ETH or all altcoin? Besides, i don't see anyone would use kBTC aside from Kraken itself and some active Kraken customer.
I think we can mention WBTC, CBBTC, renBTC, pBTC, WRBTC, teleBTC... Among them, WBTC is the most well-known, but I've never owned or used it.
kBTC is a product aimed at Kraken users. It could be a tool for Kraken to incentivize users to stay on their platform rather than exploring other CEXs in the market. I hope Kraken will see positive impacts from this new product, gaining more users and revenue to combat the SEC in the future.
