Since I am not a big user of Coinbase, I am not using its cbBTC and I am not planning to do so in the near future. Of course, Coinbase users may opt to use this another alternative and it is all up to them to be aware of what they are getting into. As long as there is no deception or lies in promoting this asset, that would be fine with me. We should note that it is our responsibility to know, analyze and decide what are the things we use, invest on and essentially getting our nods. Now, with all the things this cbBTC is bringing, I don't really see whether this can be bad or good for Bitcoin...maybe this can however be bad for those who are using them in case something will happen with Coinbase.
